某型伪码测距雷达的数字AGC设计

Design of a Digital AGC in a PN-code Ranging Radar

论述了某航天器伪码测距雷达接收机外部AGC的设计原理和具体实现,并重点讨论了如何根据射频前端的输出来设计全数字AGC,来扩展接收机的动态范围。该文的讨论对于DS-SS(扩展频谱数字)接收机和伪码测距雷达接收机的数字AGC设计有参考意义。

This paper analyses the design and implementation of an external AGC system for a PN-code ranging radars receiver in an space vehicle, and focuses on discussing of how to design an all-digital AGC according to the output of the front-end device to extend the dynamic range. The discussion of this paper is valuable for the design of digital AGC in DS - SS（ Direct- Sequence Spread-Spectrum ） receiver or in PN-code ranging radar receiver.
