摘　　要：机载雷达作为提高直升机武器平台作战效能的倍增器,受到各国军队的普遍关注。如何评估其作战效能,提高部队战斗力,是当前亟待解决的问题。在传统波动方程基础上,利用限定上、下传播边界和基于Beilis Tappert平移变换法处理地形要素的宽角抛物方程算法,仿真分析了直升机雷达在标准大气、实际大气和地形遮蔽条件下的电波传播特性。为指挥员进行战场准备,实施正确战略决策提供依据,为评估雷达性能的后续研究提供理论支撑。The airborne radar was general concerned as a multiplicator to improve the operational effective- ness of military helicopter by many countries＇ Army. The current serious problems were how to evaluate their operational effectiveness and improve combat effectiveness. The helicopter radar radio wave propaga- tion characteristics in the conditions of standard atmosphere, the real atmosphere and terrain masking were analyzed by the wide-angle parabolic equation algorithm based on the traditional wave equation, limited propagation boundaries and the Beilis Tappert translation method. The theoretical support was provided for the battlefield commanders to prepare for the battle and make the right strategic decision, meanwhile, for the follow-up study to evaluate the performance of the airborne radar.
