摘　　要：提出了一种用来计算调频连续波（ＦＭＣＷ）雷达目标逆向电磁散射场的实用渐近计算方法。在以圆柱形导体为埋藏目标模型的基础上，给出了周围介质特性、目标尺寸、埋藏深度、雷达信号频率以及电磁波的入射角度对目标逆向散射场影响的数值计算结果。This paper describes the calculation of scattered field of targets，whichare embedded in dielectric half－space，by using an asymptotic method．The result is simple and clear And some numerical results are given for conducting circular cyl－inder to show the effects of inhomogeneity of the surrounding medium，size of thetarget，depth of embedment，frequency of the radar signal and the angle of incidenceon the scattered field.
