对EW和ESM接收机的要求愈来越高。信道化接收机是能够满足或者超过这些要求的接收机类型之一。本文说明信道化接收机在目前的成功主要依赖于表面声波滤波器、微处理机、微波集成电路等领域的技术进步。同时还对目前研制的两个系统做了简要说明,这两个系统都大量地采用了表面声波器件。最后还简要论述了多路滤波器怎样实现最佳化。
The requirements for EW and ESM receivers are getting higher and higher. Channelized receivers are one of the types of receivers that can meet or exceed these requirements. This article shows that the current success of channelized receivers relies mainly on advances in such areas as surface acoustic wave filters, microprocessors, and microwave integrated circuits. At the same time, a brief description is given of the two systems currently being developed, both of which have largely adopted surface acoustic wave devices. Finally, it briefly discusses how to optimize the multi-path filter.
