摘要
频率步进雷达是一种距离高分辨率雷达 ,运动补偿是其实现距离高分辨的关键。在波形熵法用于毫米波频率步进雷达运动补偿的研究中 ,针对步进频率信号波形熵的局部最小值问题 ,采用Costas编码改进 ,并对波形熵的定义进行了优化 。
Frequency stepped radar is a high range resolution radar, and motion compensation is the key technique to realize high resolution of range. In the research of applying waveform entropy method to motion compensation of MMW frequency stepped radar, aiming at the local minimum problem of waveform entropy of frequency stepped signal, a frequency code Costas code is used and optimization is made in the definition of waveform entropy. Satisactory simulation results are obtained. [
