比幅和差式单脉冲雷达微波和差器建模

在定向雷达中，微波和差器的不理想性，对单脉冲雷达定向特性构成了一定的影响，这种不理想性主要由组成和差器的微波桥各端口的小失配形成。为了模拟这种影响，对三通道单脉冲定向雷达微波和差器进行了分析，建立了微波和差器仿真用模型，应用这一模型可以模拟构成和差器的微波桥端口小失配对单脉冲雷达定向特性的影响。这在分析单脉冲雷达定向性能、时域仿真研究单脉冲雷达抗干扰性能等应用中是有意义的。

Model for Microwave Sum and Difference Network of Monopulse Radar with Amplitude- Comparison

In directional radar the directional characteristic is affected by nonideal sum and difference performance caused by small mismatch of microwave bridge port. The microwave sum and difference network of monopulse directional radar with three channels monopulse is analyzed and the model for microwave sum and difference network is established. This model is used to simulate the impact of monopulse on the directional characteristic. The model is important not only to the directional performance analysis while microwave bridge port in siate of the small mismatch, but also to the monopulse radar simulation of anti-jamming.
