-
摘要: 本文就频率步进脉冲距离高分辨一维成像的速度补偿的常用的几种方法(时域法,频域法,最小熵值法)进行了分析和比较。并就其中的时域法和频域法进行了改进,将二者结合起来,使之更有效地对速度进行估计。还分析了速度补偿的精度要求。Abstract: In this paper, we present three different kinds of motion compensation methods for stepped frequency radar, which are time domain compensation method, frequency domain compensation method and mini entropy compensation method. Then, an improved method by combining the time domain method and frequency domain method is provided. Finally, the motion compensation requested from stepped frequency radar is also mentioned.
