一、引言本文讨论在出现海面多路径反射时,用不稳定单脉冲雷达的接收回波测量到达角的精度。特别指出了在海平面上方位角和仰角的误差是许多参数的函数。研究的目的是为了论证,在船纵横摇摆和海面多路径反射的情况下,即使沿着主天线轴的单脉冲雷达的误差很大,海面内的方位角误差也是不太大的。 I. INTRODUCTION This paper discusses the accuracy of the arrival angle measured by the receive echoes of an unstable monopulse radar in the presence of multipath reflections on the sea surface. In particular, the error of azimuth and elevation at sea level is a function of many parameters. The purpose of this study is to demonstrate that azimuthal errors in the sea surface are not large even with large monopulse radar errors along the main antenna axis, both in the case of ship-to-roll and surface multipath reflections.
