摘　　要：针对米波雷达测高中同源多径的分辨难题,对米波雷达回波信号中直射信号和反射信号进行分析,引入乘积因子的概念,建立了考虑地球曲率时乘积因子与角度(直射角和反射角)的简单函数关系,并据此提出了考虑乘积因子的米波雷达多径阵列信号综合模型。仿真实验及实测数据处理结果均表明了此模型在米波雷达测高应用时的有效性。For the multipath reflection problem in the meter-wave radar height-finding, a conception of product factor was introduced by analyzing the relationship between direct signal and indirect signal in the meter-wave radar received signals, and it was found that the product factor was the function of angles including direct angle and indirect angle. The function was constructed in the case of accounting for earth＇s curvature, and a meter-wave radar multipath array compositive model considering the product factor was proposed herein. Computer simulations and real data processing results show the effectiveness of the proposed model under the condition of meter-wave radar height-finding.
