一、引言现代电子战(EW)系统的应用特点是在多个威胁信号下须实现宽带工作。这种复杂的处理技术的核心是必须完成限幅、检波、耦合、开关、频率产生、低噪声、中/高功率放大,滤波、衰减、移相、频率分选、频率转换、数字式RF存储、脉冲延迟、噪声产生、频率测量以及天线接收和辐射等微波线路功能。在研制灵敏的小型EW系统时,新颖的微波设计技术起到了主要的作用。现代EW系统已经采用了灵敏的计算机用以控制微波线路,通过RAM或ROM修改线路而毋需改变微波硬件。
I. INTRODUCTION The application of modern electronic warfare (EW) system is characterized by the need to realize broadband work under multiple threat signals. At the heart of this sophisticated processing technique is the ability to limit, detect, couple, switch, frequency produce, low noise, medium / high power amplification, filtering, attenuation, phase shifting, frequency sorting, frequency conversion, digital RF storage , Pulse delay, noise generation, frequency measurement, and microwave line functions such as antenna reception and radiation. In the development of sensitive small EW system, the novel microwave design technology has played a major role. Modern EW systems have used sensitive computers to control the microwave lines and modify the lines through RAM or ROM without changing the microwave hardware.
