一种稀疏宽带信号全控守接收机的设计方法

Design Method of Sparse Broadband Signal Full Probability Interception Receiver

对于天线接收的多个稀疏宽带信号,通常需要多个完全独立的接收处理通道才可以实现多个稀疏宽带信号的全控守。文章论述的接收机对输入的多个稀疏宽带信号分别进行变频,使变频后的信号同时处于一个采样带宽内,并且相互之间保留一定保护带,再通过后端单通道高速AD对采样带宽进行采样,实现所有稀疏宽带信号的数字化接收、处理,从而达到全控守的目的。

For multiple sparse broadband signals received by the antenna,multiple completely independent receiving and processing channels are usually required to realize multiple sparse broadband signal full probability interception.The receiver discussed in this paper performs frequency conversion on multiple input sparse broadband signals respectively,so that the signals after frequency conversion are within a sampling bandwidth at the same time,and certain protective bands are retained between each other.Then,the back-end single-channel high-speed AD is used to sampling bandwidth to realize the digital receive and processing of all sparse broadband signals,thus achieving the purpose of full probability interception.
