SIGINT SIMPLIFIED

D-TA Systems has created sensor processing solutions that use the 10 Gigabit Ethernet backbone, instead of computer bus, for high speed data transfer between signal acquisition and processing modules. Appropriately termed 10 Gigabit Sensor Processing, the approach can handle the demanding requirements of high-bandwidth and high channel-count requirements of today’s military sensor systems. D-TA’s 10 Gigabit sensor Processing sustains data throughput rate close to the line rate (>1 GBytes/s per fibre) with no loss of data. D-TA’s design also ensures virtually limitless scalability and fully synchronous operation irrespective of the number of fibers (networks) used. Furthermore, D-TA’s 10 Gigabit Sensor Processing is OS agnostic, facilitating greater software portability. The use of optical fibers allows separation of signal digitization and processing functions over long distances, permitting digitization close to the sensors.

10 GIGABIT SENSOR PROCESSING | FAST, SCALABLE & SYNCHRONIZED

To facilitate user development D-TA has also developed a software

development framework for real-time processing of high-speed network

(sensor) data using multi-core servers.

READY-FOR-ACTIONSIGINT SOLUTIONS THAT DRASTICALLY CUT DEPLOYMENT TIME & COST

D-TA provides software development kit (SDK), application examples and hands-on training to speed up user development. For many applications, including real-time recording and playback, D-TA provides complete solution and no user development is required.

For SIGINT (both COMINT & ELINT) D-TA offers gapless spectrum monitoring from 1 MHz to 18GHz, extendable to 40 GHz, and bandwidths from a few MHz to 500 MHz for both single- and multi-antenna applications.

D-TA’s 10 Gigabit network attached sensor interface solutions provide ‘end-to-end’ coverage for demanding radio, radar & sonar applications. The user is freed from having to develop and test complex RF, IF and data acquisition subsystems, instead only focuses on software application development.

D-TA Systems caters to the EW Systems market with ready-to-run solutions that drastically cut deployment time & cost. D-TA has created an array of innovative sensor interface solutions that connect seamlessly to off-the-shelf servers using the high speed 10 Gigabit network (fiber).

D-TA’s products support deployments in land, air & sea.

UNIQUE FEATURES OF

DTA-3290 TRANSCEIVERTunable Receive & Transmit: DTA-3290 offers both RF input (Rx) and RF output (Tx) with a frequency coverage from 20 MHz to

6 GHz. The receive and transmit systems can be independently tuned. The instantaneous BW is 40

MHz.

40GHz/s Scanning Rate: The DTA-3290 incorporates fast frequency synthesiser and outputs complex baseband (I & Q)

data for each RF scan position, thus every sample provides signal power information.

RF Input /Output switch matrix: This feature allows multiple antennas (or power amplifiers at the output) for seamless scanning

up to 6 GHz

Front-End LNA and Attenuator: The receiver input design allows users to switch in either an LNA (for low signals) or a

programmable attenuator (for large signals). This allows users to make a Noise Figure vs IP3

trade-off and prevent saturation of amplifiers and mixers in presence of large signals

LNA Out & Pre-Amp In Ports: The front-end LNA output and the Pre-amp input are accessible for handling a variety of inputs

and adding customized filtering.

Digitally Programmable Attenuators: Up to 3 programmable attenuators (with 1 dB steps) are available for users for programmable

gain control and also to calibrate gain over the 6 GHz frequency range of operation.

Integrated 16-Bit Data Converters and a Large FPGA:The ADC & DAC stages are designed to offer best performances with the RF UCON & DCON

modules. These choice of sampling frequency, intermediate frequency, receiver gain and filtering

are all carefully selected for this reason. The on-board FPGA provides user-programmable DDC

function for bandwidth selection.

10 Gigabit Network: Like all D-TA products, the DTA-3290 implements a 10 GbE network (FPGA based) for

high-speed data transfer to DTA-1000R server. Because of very high throughput rate, multiple

DTA-3290 can be dropped on the same network. The control network is a separate 1 Gigabit

network.

Illustration of the DTA-3290 DDC (FPGA based) operation for IF to baseband conversion. The process of baseband to IF up-conversion for the transmit part, involves digital interpolation and bandshifting for producing a 75 MHz IF output for RF up-conversion to desired frequency.

Digitally Programmable Attenuators: Up to 3 programmable attenuators (with 1 dB steps) are available for users for programmable

gain control and also to calibrate gain over the 6 GHz frequency range of operation.

RFvision-1Recording:RFvision-1 system includes 8 TB of storage to provide over 10 hours of recording / playback at full

bandwidth (40 MHz) of complex baseband data (I & Q). The SigInspectorTM 1 GUI allows software

based scanning of the entire spectrum (20 MHz – 6 GHz) or parts thereof. The scan BW is 40 MHz,

at each step the power in the band is plotted in a waterfall display. Four windows offer a variety

of views into the spectrum captured. The first is the waterfall display, which displays power as a

function of frequency and time. An occupancy plot shows signal power as a function frequency in

the latest scan. An occupancy log lists tuning frequencies for which the power exceeds the

threshold (programmed during configuration). The fourth window provides a snapshot FFT display

of any band of interest.

If a signal is of interest, it may be recorded by clicking the “record” button. During recording a

snapshot FFT display is provided for data quality check. Recording can be stopped at anytime by

clicking the stop button.

The recorded sessions are listed in the Library View. The display provides session name,

description and recording time to facilitate file transfer / playback.

File Transfer:Recorded data can be transferred to user computer for post-processing. This process is handled

by SigInspector GUI. The destination can be any windows shared folder on the network. The file

transfer window is opened by clicking the transfer button. The entire session can be transferred by

default, or the user can select a partial session by duration or by file index. For direct access of

stored data by MATLAB a file transfer script is available. Contact factory for other popular

programs for post analysis.

RF Playback:A recorded session can be played back by clicking the “Play” button. The user can choose to play

back all or part of the session. The Advanced Playback Options window allows RF up-converter

tuning from 20 MHz to 6 GHz and gain control.

MATLAB Data Generation:The RFvision-1 also offers MATLAB based

data generation for later playback. Arbitrary

waveforms can be created or imported from

other environments using standard tools

available in MATLAB. Data is streamed to the

DTA-1000R recorder as it is generated,

eliminating need for large storage. The

generated session will appear in

the GUI library view and may be played

back in the same way as any recorded session.

Operator Training & System Test:The powerful long-duration RF record/

playback feature of the RFvision-1 system is

ideal for testing other radio systems by either

playing back pre-recorded data or computer

generated data. This feature is also very

important for operator training using RF

signature collected from various active

conflict regions.

RF Signals Library & Data Distribution: Recorded RF data can be transferred via the 1

Gigabit network to the user host computer.

The record/playback control software GUI

includes controls to manage data archiving

and file transfer to and from the recorder. The

typical transfer rate is 40 Mbytes/s.

Recorded data can also be transferred to back

up hard drives for creating an RF signals

library (mission data) by moving the recording

media to the DTA-5000 Backup system that

holds up to 32drives. RAID 5 scheme is used for

high reliability. The Back Up system can also be

used for analysis and to duplicate mission

data files for distribution to different training

centers or test sites.

Scan & Set-On Mode of Operation:Multiple DTA-3290 transceivers can be networked to the same server to support simultaneous

“Search & Track” operation. In a two receiver arrangement, one receiver is continuously scanning the

RF spectrum, while the other tracks a particular activity. The SigInspector™ 1 (Advanced) supports this

mode of operation for two or more receivers. The configuration shown here can also be used to

increase the stare bandwidth to 160 MHz (for fast frequency hop signal detection) by band stitching.

D-TA offers Software Development Kit (SDK), application examples and hands on-training to speed up user application development. Two replicated 10 GbE links are available to support user processing while recording.

User Application Development

The recorded data files can be transferred to user computer for analysis via the 1 GbE network. The typical transfer speed is anout 40 MBytes/s. For user convenience, D-TA provides MIDAS BLUE PLATINUM or MATLAB file support. Other formats can also be supported.

Post-Processing of Recorded Data

SigInspector™2 Software The basic SigInspectorTM software provides manual or automatic scanning, waterfall display and

ultra-wide band (500 MHz) recording and digital and analog (optional) playback. This software is

provided free with every shipment. The SigInspectorTM (Advanced) software provides channelization

of the 500 MHz band into 64 narrowband channels, recording of selected narrowband channels

and transfer of up to two narrowband (I & Q) data via the 1 GbE network.

Search & TrackWith two DTA-9590 ultra-wideband receivers connected to the same server it is possible to

perform simultaneous search & track (‘scan & set-on’) operation. One receiver scans continuously

while the other is set to track a particular activity. The SigInspectorTM 2 (Advanced) software

supports this mode of operation. Note that while the search bandwidth can be as wide as 500

MHz, the track bandwidth can be set lower for increasing analysis resolution. Contact factory for

details.

Bandwidth Extension to 1 GHz & BeyondThe configuration shown here can also be used to extend the BW to 1 GHz (by band stitching two

independently tuned 500 MHz bandwidth systems). The 4U system as shown can be duplicated to

extend the bandwidth to 2 GHz. Note that the frequency range can be increased to 40 GHz by

using a RF Block Down Converter. Contact factory for more information.
