摘　　要：两点源干扰是对单脉冲雷达实施角度欺骗的重要手段,但在实际工程中由于机载平台位置和姿态的快速变化,以及采样、数字处理和时钟同步等原因,使得实现两点源间高精度相位同步比较困难。为了便于工程应用,通过对对抗双方建立数学模型,在对角度测量偏差统计特性分析的基础上,提出基于幅度比控制的两点源角度欺骗干扰方法,并进行仿真验证,仿真结果表明该方法可以实现稳定、有效的干扰效果。The dual-source interference is an important method of angle deception jamming on monopulse radar. But for practical engineering, it is difficult to realize high precision phase synchronization of dual sources due to rapid change of position and attitude of airborne platform, as well as sampling, digital processing, clock synchronization and other reasons. In order to use it in practice, by building a mathematical model for both sides of the engagement, and on the basis of statistical analysis of angle measurement error, a method of dual-source angel deception jamming based on control of amplitude ratio is proposed. Then this method is verified by simulation, and simulation result shows the jamming performance achieved with this method is steady and effective.
