This radar has been specifically designed for the accurate measurement of the speed and range of passing vehicles when mounted at the side of the road for enforcement purposes. The radar is designed to work in conjunction with an AGD340 radar plus a host, photographic based, enforcement system. The host system may be mobile or fixed location in nature. The radar is supplied in a black plastic enclosure which incorporates all the radar circuitry and processing circuitry to perform the speed and range measurement. The connection to the radar is via a 1 metre cable with multi-pin connector, and mounting is provided by fixings on the housing. The AGD315-205 is a 24.2GHz frequency modulated continuous wave (FMCW) radar whereas the AGD315-207 is a 24.125GHz (24.075GHz-24.175GHz) radar which are capable of measuring range and speed. The radar’s integral planar antenna forms a narrow beam which is sited at a predetermined angle across the road. When vehicles pass through the beam the radar accurately measures the speed and range at a frame rate of 40 readings per second via an advanced digitising and tracking technique to a resolution of approximately 1 mph and 2 metres. Details of each vehicle speed measurement are passed to the host system via a high speed serial communications interface.

When this signal strikes a target, the signal will be reflected back and received by the radar at a time t=t delayed . During the time of flight of the reflected signal. the transmit frequency will have increased to a new frequency f delayed , where f delayed is given by the chirp rate and amplitude. Hence at any instance in time after t delayed , there is a difference in frequency between the transmitted and received frequencies. This frequency difference is proportional to the time of flight for the received signal, and since the radar signal travels at the speed of light (a constant), the time of flight is also proportional to the range of the target which reflected the radar signal. In an FMCW system, the transmit and receive signals are compared using an RF Mixer. The mixer is driven by the transmit and receive signals, and the mixer output is the difference between the two input signals. The output signal is referred to as the intermediate frequency (IF). If the IF is sampled into an analogue to digital converter (ADC) at fixed time intervals during a single excursion of the frequency modulation (one period of the chirp) and the resultant digital signal is viewed in the frequency domain, a number of different frequencies will be seen, where each frequency corresponds to a target at a particular range. If data from a number of successive chirps is gathered and processed, speed and range for individual targets can be determined. , © AGD Systems Ltd 2010.
