摘要
现代雷达为获得较高的距离分辨力通常采用编码频率脉冲串信号和步进频率脉冲串信号,但都存在数据率低和较为严重的距离-多普勒耦合问题。在研究这两种信号特点的基础上,提出了调频编码脉冲信号形式并给出了相应的信号处理方法。经仿真对比可见,该信号形式及其处理方法能同时解决步进调频信号高距离-多普勒耦合、低数据率两大问题,具有较好的联合分辨力。
In order to improve radar resolution, the frequency-stepped pulse signal and coded frequency signal are widely used in a modern radar system. But these signal problems of range-Doppler coupling and low data ratio are still not solved completely although some encouraging results have been obtained and applied in the radar system design. Based on studying their characteristic, this paper presents radar frequency modulation coded pulse signal and develops its processing method. Through simulation and comparison, this signal can solve both problems simultaneously and has a preferable combined resolution .
