遥测系统中高数据率扩频传输及其伪码快捕技术的实现

Realization of High Data Rate Spread-Spectrum Transmission and PN Code Fast Acquisition Technique in Telemetry System

根据遥测系统发展的方向,把编码扩频技术应用于传输频带的压缩,对编码扩频捕获与跟踪进行了理论推导,并采用伪码快速捕获的方法,解决了编码扩频技术在实际中的应用问题,适合于新体制下遥测图象信号的抗干扰保密传输。

Applying coded spread spectrum technique to compressing of frequency-band transmission, the acquisition and tracking theory of coded spread spectrum are analyzed. The problem of actual exercise with the coded spread spectrum technique has been solved by the way of fast acquirement PN. It has been propitious to transmit the anti-jamming secrecy remote-measure image signal in new system.
