以单站无源定位系统项目开发为背景，研究设计了该项目的接
收机系统。文章首先根据系统需要制定了接收机的总体设计方案，将接
收机分系统划分为两个子模块，包括高频接收机和宽带数字接收机，文
章分两个部分讲述了高频接收机和宽带数字接收机的设计过程，并分别
对这两部分的性能进行了测试。(This paper explores the receiver system of the project in a single passive
locating base. First, the paper sets down the total precept of the receiver. The
receiver system is composed of high-frequency receiver and broadband digital
receiver. The two subsystems have been detailedly discussed in two parts of
the paper.)
