摘　　要：逆合成孔径雷达(ISAR)成像仿真的先提条件是要有信号回波,所以首先要建立目标回波模型。本文主要根据一个具体飞行目标,建立立体目标回波模型,再由雷达回波原理,计算得到目标相对于雷达不同位置的回波信号,其中包括考虑遮挡影响,采用传统的距离-多普勒(R-D)成像,对所建立的回波信号进行成像仿真。The premise of ISAR imaging simulation is echo signal of target, so the first thing of simulation is establish the model of echo single. The paper produces the echo model of solid target base on a certain aircraft, then with the principle of radar echo, we can account the echo signal of various positions relative to radar, which including the influence of barrier in one type model imaging of echo signal with the method of Range - Dopple（ R - D）.

关 键 词：ISAR成像 目标回波 立体模型 遮挡
