针对传统调频连续波(FMCW)雷达难以实现多目标准确配对的问题,提出了一种变斜率FMCW雷达调制波形,能有效实现多目标的准确配对.并在此基础上,提出了一种时域抽取和频域内插方法,使得更靠近雷达的目标,能获得更优的距离和速度测量精度.仿真结果证实了该方法的有效性.%To solve the multi-target pairing problems for traditional Frequency Modulated Continuous Wave (FMCW) radars, a new FMCW radar signal with changing slope was proposed, enabling more accurate targets pairing. Based on this signal, in order to get better range and velocity accuracy for near range target, decimation in time domain and interpolation in frequency domain can be used. Simulation results show us the effectiveness of this method.
