336The AGD336 is a compact FMCW low power digital radar which operates in the K-Band 24GHz. The radar processing consumes approximately 150mW whilst maintaining an active GPRS connection and radar update rate of 16Hz. The power can be reduced further by increasing the period between GPRS events. Configuration of operational parameters is via an GPRS Modem. Detect output is via a XML packet structure over GPRS Modem.

QUICKSTART GUIDE

1 CONNECTING POWER

Connect the red wire from the 336 to the positive DC supply. The blue wire should be connected to the negative of this same supply. Once powered, the 336 front and rear LED should flash for approximately 2-3 minutes as the 336 registers onto the GPRS network.The flash rate changes as it goes through the different stages 6V/12V Power supply AGD336

2 INSTALLING THE RADAR DIAGNOSTICS SOFTWARE

Download and install the Radar Diagnostic Software from www.agd-systems.com/downloads or from the 336 Trial Kit CD.Install the Software following the on screen instructions.Launch the program by clicking the new desktop icon.When prompted, select the AGD336 button

INSTALLATION

MOUNTING HEIGHT, ANGLES, CLEARANCE

The radar should be mounted on a firm structure. The radar should point down and accross the highway at 20 degrees to the direction of traffic flow. The front face of the radar should be pointing at the base of the central reservation. The radar has a relatively narrow azimuth field of view of 12 degrees. Within this angle the target vehicles should be visible at the greatest detection distance.For optimum performance the radar should be situated on the nearside of the carriageway with an unobstructed view of receding traffic.

USER CONFIGURATION

COMMAND STRUCTURE

The Radar features user-adjustable Parameters to change the way it operates. These are accessed through Commands, sent via the GPRS Connection.

Most commands start with an Asterisk (*).

The radar shows responses to commands using a Hash (#) prefix.

Commands must be terminated with a carriage return character (<CR>), typically sent when using the <Enter> key.

The Radar will send a <CR> (carriage return) at the end of a message. COMMAND TYPES

There are 3 basic “Types” of commands, refelecting the number of ways to interact with a Parameter:

QUERY SET ACTION

Query commands show a Parameter value without changing it

Set commands change a Parameter value

Action commands perform an operation, often on a group of Parameters

TROUBLESHOOTING

I don’t see a flashing LED when connecting power1. Make sure the unit is wired correctly and power supply is set to the correct voltage, & powered on.2. If a fuse or current limiter is fitted, ensure this is working correctly or set to an adequate value.

I have checked the above & still do not see a flashing LEDIt is possible that you may have a faulty unit & it will need to be returned to AGD for inspection.

My unit does not appear to respond to commandsCheck that the LED flashes when powering on and then wait for the LED to stop flashing.

My unit is powered on but will not respond to commands1. Check the password has been entered. It will accept the AGD command without a password.2. Make sure the detector is connected to a smooth DC power supply.Connection to noisy supplies can result in transmission being blocked.3. Make sure the detector is placed in a good area for GPRS reception.

My unit won’t detect vehicles1. If you are monitoring the LED for detection confirmation you may need to increase the brightness to suit conditions (via the *LD command).2. Check the Detection Threshold setting (*DT) , if the value is low increase sensitivity as required.3. Make sure the vehicles are within the tracking limits set by the commands *LST and *HST.

Occasional targets are dropped1. Check the mounting height & alignment.2. Refer to the Command List to determine current radar parameter settings. Adjust as necessary to suit site topography and operating conditions.

Hyperion™ is a bespoke set of test equipment designed and developed by AGD Systems. It is dedicated to the testing of the AGD portfolio of ‘ranging’ FMCW vehicle radars. 100% of the 336 units manufactured at AGD are Certified by Hyperion.

The key test functions performed by Hyperion to Certify the premium performance of your Intelligent Detection System are:

• True range simulation of target

• Target speed and direction simulation at a given range

• Radar target processing optimisation

• Transmitted radar power and frequency modulation measurement

• Radar signal to noise level measurement

• Verification of interface and communication protocols

• Test cycle time of 9 minutes

The radar test sequences performed by Hyperion on the radar under test provides a thorough examination of the performance of the 336 radar and specifically the ranging measurement capability provided by the FMCW technology deployed. This gives full control of simulated targets’ signal size, speed, direction and range.

Verification of GPRS communication to the detector is verified during the test cycle.

Optimisation of frequency signals on Hyperion ensures full compatibility with country requirements within the 24GHz radar operating band.

LIFETIME PRODUCT TRACEABILITY There are clearly defined pass and fail criteria at all stages within the Hyperion test process. The test results in association with the product build revision are recorded on a product serial number basis.

IMPORTANT SAFETY INFORMATION

LOW POWER NON-IONISING RADIO TRANSMISSION AND SAFETY

Concern has been expressed in some quarters that low power Radio Frequency transmission may constitute a health hazard. The transmission characteristics of low power radio devices is a highly regulated environment for the assurance of safe use.

There are strict limits on continuous emission power levels and these are reflected in the testing specifications that the products are approved to. These Type Approval limits are reflected in the product specifications required for a typical geographic area such as those for the EU (ETS300:440), for the USA (FCC part 15c) and for Australia/New Zealand (AS/NZS 4268). The limits adopted in these specifications are typically replicated in many other localized specifications.

The level of safe human exposure to radio transmission is given by the generally accepted guidelines issued by the International Commission on Non-Ionizing Radiation Protection (ICNIRP). This body has issued guidance for limiting exposure to time-varying electric, magnetic and electromagnetic fields (up to 300 GHz) which are quoted below.

Note 1 Values are calculated conversions for comparison purposes.

Note 2 Other equivalent limits include; Medical Research Council Limit of 10mW/cm2, IACP limit of 5mW/cm2 (at 5cm) and UK CAST limit of 5mW/cm2

Note 3 Calculation is made on the assumption antenna is a point source therefore the actual value is likely to be significantly less than that quoted. Note that a theoretical max level at a 5cm distance (which gives 0.318mW/cm2) is at a point in the field where the radar beam is not properly formed.

Note 4 Comparison for product model 336 operating in the band typically 24.050GHz to 24.250GHz

From the table it can be seen that it is extremely unlikely that a potentially hazardous situation could occur owing to the use of such low power devices.

It is considered to be good practice not to subject humans to radiation levels higher than is necessary. In a works environment where multiple equipment on soak test are to be encountered then it is considered good practice to contain the equipment in an appropriate enclosure lined with radar absorbing material.
