| 摘 要： | 通过为Costas跳频雷达一维距离像定义一个波形熵，将运动补偿转化为一个一维优化问题。基于模拟退火算法的原理，提出了一种一维精确搜索算法并将其运用到Costas跳频雷达的运动补偿中。仿真表明，该算法不依赖于梯度信息，具有良好的稳健性和全局收敛性，在信噪比为0．4dB时仍能获得高分辨率的一维距离像。

| Abstract: | By defining waveform entropy for 1-D range profile of Costas frequency hopped radar, motion compensation was translated into a 1-D optimization problem. Based on simulated annealing algorithm, a 1-D accurate searching method was proposed and applied to motion compensation of Costas frequency hopped radar. Simulations show that this method is robust, globe and independent of gradient. High-resolution 1-D range profile can be obtained even at the signal noise ratio of 0.4 dB. |
