摘要：
A measurement system to detect people sitting on the rear bench of a car has been developed for which a four channel imaging radar system at 24 GHz SRD (ISM) with a bandwidth of 250 MHz is used [1]. On the radar system an antenna array with a dedicated radiation pattern is applied [2]. Based on a FMCW modulation approach it is possible to measure the range and the Doppler signal due to the motion of the passenger in the back of the car. A DBF approach is applied on the four receiver channels in order to determine the angle of arrival. Thus it would be possible to determine the seat location of the passenger. The data acquisition is done with an ADC from National Instruments. The signal processing and the evaluation of the results are performed with MATLAB.
