摘要
振幅和差法是单脉冲雷达常见的测角定向体制。在分析振幅和差式单脉冲雷达工作原理及遮盖性干扰原理的基础上,建立了基于振幅和差式单脉冲雷达的遮盖性干扰评估模型,并对建立的干扰模型进行了计算机仿真。仿真结果表明:在造成足够大的角度跟踪误差时,遮盖性干扰对振幅和差式单脉冲雷达具有较好的干扰效果。
Sum-difference method of amplitude is typically the angle-direction measurement system of mono-pulse radar. Firstly, the working principle of mono-pulse radar and the essential principle of masking jamming are analyzed. Then,jamming evaluation model is established and applied to sum-difference of ampli- tude monopulse radar,in order to evaluate the jamming effect. Lastly, this method and correlative arithmetic are simulated in computer. The simulation results show that the masking jamming effect is comparatively well, as long as the angle-measure deviation is adequate.
