摘要
本文从雷达及其武器系统目标识别的观点出发,对目标一维距离成像原理及存在的有关问题进行了探讨;提出了一种运用距离域超分辨技术对I、Q两个接收通道的数据进行处理,从而获得目标的高分辨率距离结构图像的新方法;这种方法既可以克服频谱混叠效应,又可以克服因I、Q正交误差及通道幅相不一致性所带来的估计误差,同时具有较强的抗杂波噪声性能,为解决目标成像与识别问题提供了一条有效途径。
This paper studies the theory and discusses some problems of target identification using range profile in radar systems. A novel method of obtaining high resolution range profile is presented ,which uses superresolution techniques to process data of two receiving channels(I and Q).This method has the advantages of not only avoiding spectrum folding but decreasing spectrum estimation error caused by amplitude and phase inconsistency of I and Q channels and is helpful for solving the problems of target imaging and target identification in radar systems.
