基于Li和Wang提出的提高距离分辨率有利于提高距离像的姿态稳定性这一结论，不少研究者利用超分辨距离像进行目标识别。文中从高分辨雷达目标的简单散射点模型理论出发，分析了距离像的分辨率与目标姿态敏感性的关系，并且结合仿真实验，详细分析了MUSIC超分辨距离像用于目标识别时对目标姿态、散射点个数、信噪比的敏感性等问题。

Based on the conclusion drawn by Li and Wang that radar with higher range resolution can provide better tolerance to aspect variation, a lot of work has been done on radar target recognition using super-resolution range profiles as features. Starting from the point scatter model of high-resolution radar target, we analyze the relationship between the range resolution and the target orientation sensitivity of the high-resolution range (HRR) profiles. Through simulations, We analyzed in detail the problems such as the target orientation, the number of scatterers and the signal-to-noise ratio sensitivity which should be paid attention to when using MUSIC super-resolution range profile for radar automatic target recognition.
