Turn the device on by switching the ON/OFF switch to on. (you should hear a faint “click” inside as you turn the device on and off) 3 (5) The PC software The program can be run on a computer with DOS or Windows, just make sure that the serial port (com 1) is available. The program doesn’t have to be installed on the computer, it runs from the floppy drive. • Connect the com cable to the serial port on a PC. • Insert the floppy disc in the floppy drive. • On the disc, there is folder called “ASTRO”. • Open the file called “ASTRO”, in the folder “ASTRO”. • The main menu looks like above. • Scroll up or down with the arrow keys. • Choose with “Return”. • To start the device – choose “Measure” 4 (5) • Choose what “site” you want to use (there is only one) • Choose by hit “Return” • Start the dive by hitting “Return” once more. 5 (5) • When the device is started, this screen appears. • The device makes a internal calibration every 15 min and will appear on screen as 54mph • To stop the measurement – use arrow keys and choose “stop”. • Exit the program from the main menu by choosing “Exit”. • If you get an error message when you start the measurement, turn the device off and then on again, and try again.

Transmitting frequency is 10.525 GHz. The unit is comparing the difference between the frequency sent out and the received frequency. A received frequency that is lower than the transmitting frequency indicates a car moving away from the radar and a higher frequency for a car approaching. AGC – Automatic gain controller The microwave unit sends the signal to the AGC-board. The frequency of that signal is the difference of the signals in the microwave unit. The AGC consist of filters on three different channels, A, B and C. Channel A measures the speed of the car. The difference in frequency from the microwave unit correspond to a certain speed. 1.2 kHz is 60 km/h ~38 mph. The frequency will be between 300 – 5.5 kHz. By comparing the phase shift between the A and B channel we can determine the distance to the car. DSP-unitADCAGC Microwave- unit CFARKOM Decision KOM PC104Camera Red light signal Channel C is used to make sure that the car the radar sees is not further away than 250ft. ADC – Analog digital converter The ADC converts the signal to a digital signal through a 12 bit converter. DSP – Unit Digital signal processor The DSP has a FFT – Fast Fourier Transfer, that transfers the signal by looking at the frequency and the amplitude. Here is were the data is read. The result will appear like shown below. The result will be placed in a bin. Each bin in the diagram is 3,2 km/h, and the radar only sees one each bin. That means that the cars must have a 3 km/h difference in speed to be detected. If there is two cars in the same bin the car with the highest magnitude will be measured, that will say, the closest one. Magnitude 3,2km/h Speed CFAR – Constant False Alarm Rate Noise reduction. It’s basically a filter Decisions processor It decides if it’s going to send the data to the KOM-processor or not. The speed has to be in accordance with the change of distance of the target. The red light signal is also wired to the decisions processor. KOM Processor The KOM processor is sending data to PC and camera Report Following description is for approaching vehicles. To get a accurate report, out of 10 samples, 5 has to be correct, 4 before the limit line and 1 after. If a lot of the samples are not approved, the radar keeps on trying to get samples approved. That gives sometimes a report line that “floats”. The distance to the report line will sometimes be shorter than preset. The programming allows the radar to keep looking for the car up to five meter closer than the report line. For leaving vehicles the distance to the report line will be more distant. Radar loob The angle of the loob is 13 degrees. On 40m the loob will be approx. 8 m wide, at 50 it’s 10 and at 70 it’s 15. The width above is within the area where the power of the loob is more than 50%. The radar will still measure cars outside the loob, depending of distance angle and where it’s mounted.

The EUT was scanned 360 degrees and the antenna height scanned from 1 to 4 m. The measurements were performed with both horizontal and vertical polarisation of the antenna. The antenna distance was 3 m. The measurement was first performed with average detector. The test set-up during the tests can be seen in the picture below.
