摘　　要：本文提出了一种用于毫米波汽车防撞雷达的编码步进调频连续波信号 .这种新的发射信号具有距离高分辨率特性和良好的抗干扰能力 .本文还提出了一种用于多目标环境中的试凑逼近检测算法并通过计算机仿真证明了该算法可以有效地去除虚警 .最后 ,对信号波形的优化进行了研究并给出了仿真结果 .A new transmit signal for mm-wave automotive collision warning radar applications is proposed. This signal, named Coded Stepped-FMCW, provides high range resolution and good anti-interference capability. A trial and error approach algorithm for multi-target detection is also suggested and its usefulness in eliminating the false target is confirmed by computer simulation. The optimization of waveform design is investigated and the simulation results is presented in the end.
