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。
In this paper, from the point of view of target recognition of radar and its weapon system, the principle of one-dimensional target distance imaging and the related problems are discussed. A method of using distance domain super-resolution technique is proposed for the data of I and Q receiving channels The method can not only overcome the spectrum aliasing effect but also overcome the estimation error caused by the quadrature error of I and Q and the inconsistency of channel amplitude and phase, At the same time, it has strong anti-clutter noise performance and provides an effective way to solve the problem of target imaging and recognition.
