| 摘 要： | 对于频率步进雷达的距离像抽取与速度估计问题,多数文献都是将二者分开来加以讨论和研究的.文中将距离像抽取和速度估计的问题联合起来进行了分析.首先,采用直接定位运动目标回波矩阵最大值位置的方法,修正距离像抽取的范围;其次,利用得到的一维距离像对速度参数进行估计.文中两种方法的结合,对新体制雷达的研究有一定的实用价值.最后的计算机仿真验证了该方法的有效性与理论分析的正确性.

| Abstract: | Two important problems in the researches of step frequency radar are HRR profile stitching and velocity estimation.But effective researches had been done on the two problems respectively.This paper combined the two problems together.Firstly,by finding out the max value in the echo matrix,an effective method was found to obtain the HRR profile.Secondly,by using the obtained HRR profile,the velocity was estimated.Methods mentioned in this paper may have some value for the researches of new style SF radar.The ... |
