要約(英語): This paper describes a method that can realize high resolution range-Doppler imaging for the front and lateral direction of an on-vehicle radar. A Doppler shift compensation method for millimeter wave radar using stepped multiple frequency has been proposed. This method can compensate the spread of Doppler frequency due to multiple frequency transmission, range walk and Doppler walk caused by movement of the radar in a measuring period. A high focusing accuracy in range-Doppler image is achieved even when the measuring period is long using this method. The proposed method is verified by computer simulation and by applying it to a field experiment result using a corner reflector and a vehicle for targets of the radar. And this paper also describes the fast processing by using FFT for Doppler frequency spreading correction and range walk compensation with large processing load, and shows the results of Doppler imaging by this method.
