摘要
本文讨论ＭＵＳＩＣ算法用于频率步进毫米波雷达高分辨率距离像的成像方法，分析了ＭＵＳＩＣ算法具有分辨率高、旁瓣效应低、抗噪能力强，能给出目标尖峰值估计，从而改善距离像质量的原因。利用简化的目标散点模型进行了计算机仿真，表明采用ＭＵＳＩＣ算法可获得更好的目标距离像，有利于提高雷达目标的识别率。
In this paper, we study the method of imaging for frequency-stepping high resolution range profile with MUSIC algorithms. The high resolution and decreasing spectrum estimation error of MUSIC are analyzed. By use of the echo model, the computer simulation was carried out. The simulation results show that the method is able to obtain high resolution range profile of target and has good performance of target recognition with MUSIC algorithms.
