A Study of Angle Measurement with Monopulse for Sparse-Array Synthetic Impulse and Aperture Radar

研究了稀布阵综合脉冲孔径雷达（ＳＩＡＲ）基于单脉冲测角的原理、方法及其工程实现，推导了测角误差函数，讨论了距离、方位和仰角之间的耦合影响，提出了一种消去比相法测角时方位和仰角之间耦合效应的简便方法。最后通过计算机仿真证明了ＳＩＡＲ采用这种方法进行角度测量与目标跟踪的可行性。

This paper studies the principle and method of angle measurementt with tnonoputhe for sparse- array synthetic impulse and aperture radar(SIAR),drives the error functions using angle measure-ment,discusses the coincidence effect among distance,azimuth and elevation, and precents a simple way for de leting the conciden ce effect between elevation and azimuth in angles detecting with phase-compa rison monopulse,Finally,computer simutation results show this method is effective.
