一种新颖的前沿检测接收机的设计

A Novel Design on Leading Edge Detection Receiver

针对当前前沿检测接收机存在着虚警概率大的不足,设计了一种新颖的前沿检测接收机。通过采用隧道二极管门限检测器、回波信号多通道分时处理和可编程逻辑器件内引入延时的方法,使其实现了高灵敏度、恒虚警检测和消除近区响应。设计的接收机简单、可靠、易行,对提升同类接收机性能有一定的借鉴作用。

For the too big false alarm probability of existing leading edge detection receiver,a novel leading edge detection receiver is designed.By using tunnel diode threshold detector,multi-channel and time-sharing processing of echo signals and delay introduced in programmable logic devices,the receiver realizes high sensitivity,constant false alarm rate（CFAR） and no effect of the things around it.The design of receiver is simple,reliable and facile.It is useful to promote the same kind receiver.
