摘要
交叉眼技术是对抗单脉冲雷达最有效的方式之一.针对交叉眼干扰多侧重于仿真建模、实验设计及实施复杂等特点,基于交叉眼干扰原理、单脉冲测角原理和矢量网络分析仪幅相精确测量等特性,设计了基于喇叭天线、微带天线、幅相调节器和非脉冲矢量网络分析仪组成的非反向交叉眼干扰实验系统.在微波暗室环境下,先后开展了基于矢量网络分析仪的测角实验和非反向交叉眼干扰实验,并通过建立干扰天线相位中心电磁仿真模型,对误差展开了分析.实验和仿真结果表明:交叉眼干扰下实验测量的角度值与理论角度值随相位差变化趋势一致,其理论最大角度值与实际最大角度值误差不超过2°,对应的交叉眼增益误差小于0.5;基于矢量网络分析仪设计的非反向交叉眼实验系统可行,可模拟非反向交叉眼干扰对被动单脉冲雷达干扰,亦可部分模拟反向交叉眼干扰应用场景,为交叉眼干扰机设计和测试提供一定的指导.
Abstract
Cross eye technology is one of the most effective ways to counter monopulse radar.For cross eye interference,the simulation modeling,experimental design,and implementation are more complex.Based on the principle of cross eye interference,the principle of monopulse angle measurement and the accurate measurement of amplitude and phase of vector network analyzer,a non-retrodirective cross eye interference experimental system is designed based on horn antenna,microstrip antenna,amplitude and phase regulator,and non-pulse vector network analyzer.In the microwave anechoic chamber environment,the angle measurement experiment based on the vector network analyzer and the non-retrodirective cross eye interference experiment are carried out successively,and the error is analyzed by establishing the electromagnetic simulation model of the phase center of the interference antenna.The experimental and simulation results show that the change trend of the angle value measured experimentally and the theoretical angle value with the phase difference under the cross eye interference is consistent,the error between the theoretical maximum angle value and the actual maximum angle value is lower than 2°,and the corresponding cross eye gain error is less than 0.5.The non-retrodirective cross-eye experimental system designed based on the vector network analyzer is feasible,which can simulate the non-retrodirective cross eye jamming to the passive monopulse radar,and can partially simulate the retrodirective cross-eye jamming application scenarios,providing some guidance for the design and testing of the cross-eye jammer.
