System Hardware

Suitable for where Antennas are platform mounted.Display unit can be handheld (as shown) or full ESM MMI on Laptop (see later)


System Hardware (Mast Mount/Remote)

Mast-Top unit contains all except display unit – suitable for mast-top & remote site operations


Example Operational Context (1)

System hardware and display mounted in vehicle



System hardware mounted in vehicle – Display carried by foot patrol



System hardware mounted in UAV – Data relayed via UAV control centre. Display carried by foot patrol


Signal Conditioning - RR017• 4 RF ports into two simultaneous Video/RF channels

( option for 360 degree instantaneous FOV )• Rejection of out-of-band signals• Switched attenuation (for large signals)• Dual DLVA• Automatic (in-pulse) selection of IFM signal• Automatic PDW Generation• Detection & Declaration of CW signals


RR017 4 Port – 2 Channel Wideband Rx


Threat Processing

• Waveform Based Processing Algorithm• High pulse density (>1 million pulses per second)• Fast reaction time (typically < 1 second)

– Ability to cue fast set on ECM capability• Insensitive to receiver/digitiser colouration• 5000 threat mode library (expandable)• 500 entry track table (expandable)


Handheld Display

• PDA-based unit (incl WiFi & quad band GSM)

• No operator intervention• Audio and visual alarm • Display centred around sensor

location• Up to 30 threats displayed

(expandable)• Also displays own lat/long (via

internal GPS)• MIL STD 2525 Symbology (can

host User Defined set)• Application portable to other host

processors


Full ESM MMI• For use by EW Analysts• Full Tactical Displays

– Map/Imagery– Polar– Graphical

• 500 entry Track Table with parametric details

• Supports display of platform/weapon data

• MIL STD 2525 Symbology (can host User Defined set)

• Application can be hosted on existing user IT systems


Operational Support

• Library Generation tool can be integrated with national source databases

• Library entries can also be generated locally from own sensor PDW collection or from PDW data collected by other sensors

• Note:1 x system may also be required at Op Support unit for Library validation
