摘要

由于目标微动特征能够确定目标一些独特的性质,因此利用高分辨雷达信号对目标的微动参数进行提取,对于目标的分类、识别、成像具有重要意义。频率步进雷达信号作为一种重要的高分辨雷达信号,已经得到了广泛的应用。文中研究了微动目标的成像特征提取方法,实现了对目标微动参数的提取,同时分析了速度估计误差的影响,并给出了相应的参数设计准则,最后通过计算机仿真结果表明文中方法简单有效。

Abstract

The specialty of micro-motion can be used to determine some natures of the targets. The extraction of the micro-motion parameters of targets by using high-resolution radar signal has great importance on the classification, recognition and imaging of targets. Steppedfrequency radar technology is one of the common approaches to generate high range resolution profiles(HRRP). In this paper, the issue of micro-motion parameters extraction was concerned based on stepped-frequency waveform. A method of extracting the micro-motion parameters based on the HRRP was analyzed. Moreover, the influence of the velocity estimation error was analyzed, and some guidance on parameters design was also proposed. Finally, simulation results indicate that the method can effectively extract the micro-motion parameters with low computational cost.
