摘　　要：SIAR(稀布阵综合脉冲孔径雷达)是一种全新的数字综合孔径米波四坐标雷达。文中介绍了这种雷达试验系统的主要原理,针对该雷达在测高方面的不足给出了一种基于距离高分辨的多路径测高方法。该方法通过分辨出新型宽带SIAR的多径信号回波,获得了对测高精度的改善。并对这种测高方法进行了分析和仿真,证明了该方法的有效性。Sparse-array Synthetic Impulsed Aperture Radar（SIAR） is a new all digital synthetic aperture four dimension metre-wave radar. This article presents the theory of SIAR, and gives a multi-path height measurement method which is based on high range resolution to overcome the defect in height measurement. The method improves the height measurement precision through identification of the multi-path echo signal in new wide band SIAR. The article also a detailed analysis and the simulation of the height measurement method which shows presents its validity.
