扩谱雷达系统设计

THe System Design of the Spread Spectrum Radar

将扩谱技术用于雷达系统，将使雷达具有许多优良性能。诸如良好的抗干扰性和低截获概率性；高的距离和速度分辨力；易于解决作用距离远和距离分辨力之间的矛盾等。本文首先简要论述扩谱的基本原理，接着较为详细讨论扩谱雷达系统中要解决的几个主要问题。对于收发合一的扩谱雷达必须解决的收发隔离问题，本文提出了一种采用ＦＨ－ＤＳ混合扩谱系统的方案。

The system design of the spread spectrum radar is an important problem. In this pa-por the principle of spread spectram is briefly introduced and it 's detailed discussed how to determine the principal parameters of the spread spectrum radar.The FH-DS spread Spectrum system is pres-ented. The system is used to solve the isolation between the transmitter and the receiver when an an-tenna is sharec by the transmitter and the receivcr.
