| 摘 要： | 基于调频步进雷达信号是一种速度敏感信号,需要进行严格的运动补偿,文中详细推导了调频步进雷达信号2次脉冲压缩处理的理论表达式,分析了目标运动带来的距离耦合项,并对经典运动补偿方法进行了理论推导和研究。同时,还提出利用步进频体制的距离-多普勒耦合效应,只需一次补偿的新方法,仿真实验验证了该方法的有效性。 |
| 关 键 词： | 调频步进 运动补偿 距离-多普勒耦合 |

| Abstract: | As the linearly modulated stepped frequency(LMSF) radar signal is sensitive to velocity,it requires accurate velocity compensation.According to this,the theoretical expression of twice match-filter processing of LMSF radar signal is derived in detail, and the range coupling term caused by target motion is analyzed,and the processing effect of classical velocity compensation is also analyzed in this paper.Based on this,a new velocity compensation method is proposed by using the range-Doppler coupling. Simulation results verify the validity of the new method. |
| Keywords: | LMSF velocity compensation range-Doppler coupling |
