Channelised receiver. A viable solution for EW and ESM systems

The requirements of EW and ESM receivers continue to become more and more demanding. The channelised receiver is one receiver type that can often meet, or exceed, these demanding requirements. The paper presents discussion suggesting that he recent success of the channelised receiver is largely due to technology advances in areas such as surface-acoustic-wave filters, microprocessors and microwave integrated circuits. The paper presents a brief description of two recently developed systems, both of which make extensive practical use of surface-wave components. A brief discussion on the recurring concern of how to optimally multiplex filters is also presented.
