摘　　要：由于机载预警雷达大多采用了先进的抗干扰技术,仅进行距离欺骗,干扰容易被识别,因此还必须进行角度欺骗,形成逼真的假目标。计算假目标和预警机运动时的干扰角度延迟量,通过合理假设,对天线方向图进行绘制,建立了幅度调制模型并阐述其基本原理。最后仿真干扰对抗过程中脉冲幅度包络的变化,验证了模型的合理性。While the advanced anti-jamming is extensively applied in more AEW radar, only the distance deception is easy to be identified. At the same time the direction deception is necessary to form the fidelity false target. The azimuth jam-delay is calculated while the false target and early warning aircraft all move, through reasonable hypothesis, the aerial radiation pattern is drawn, then the model of the amplitude modulated is established and its principle of operation is introduced. With the help of simulation, the rationality of these models is demonstrated.
