| 摘 要： | 由于径向运动使步进频脉冲信号目标回波失真,而传统的时域互相关法补偿精度已不能满足要求,因此提出了改进的时域互相关法估计速度参数.该方法在采样点较少的情况下,基于初步速度估计值,并以补偿精度为速度搜索的步进量,从而缩小了速度搜索范围,在满足速度补偿精度要求的同时减少了计算量.计算机仿真结果及性能分析表明,该方法补偿精度高、对噪声的影响具有一定的稳健性,且计算量小,便于实时处理,应用价值较高. |
| 关 键 词： | 步进频脉冲信号 速度补偿 信号处理 距离像 |

| Abstract: | The target radial motion made the stepped frequency pulse echo deformed and the accuracy of the time domain cross correlation method was not satisfied with the demand.For solving this problem the advanced time domain cross correlation method was put forward.Under the condition of few sample points this method could reduce the searching range based on preliminary velocity estimation value and compensation accuracy value.So this method was satisfied with the demand of accuracy.The simulation results and perfo... |
