宽带电子战微波接收机的幅度平坦性对灵敏度的影响

宽带微波接收机是电子战系统的重要组成部分，灵敏度是宽带微波接收机的重要指标．幅频特性在电子设备中普遍存在的，理想的端口阻抗匹配在实际电路中是不存在的，这必然会引起电路的幅度起伏．根据电子战宽带微波接收机的一般构成，分析了其幅度平坦性，以及幅度平坦性对灵敏度指标影响．

The impact of amplitude flatness of broadband microwave receiver on sensitivity

The broadband microwave receiver plays an important role in the system of electronic warfare, whereas sensitivity is one of the most important characters of the broadband microwave receiver. Amplitude-frequency character is popular in electronic equipment and there is no ideal port impendence matching in the practical circuits, consequentially leading to the amplitude fluctuation of circuit. The general composition of broadband microwave receiver of electronic warfare system is introduced first, and then the amplitude flatness of broadband microwave receiver and its impact on sensitivity are analyzed.
