摘　　要：针对SMA地面多波束形成FDM变换对相干导频的需求,研究了一种对星上扩频遥测信号地面进行高精度跟踪与恢复出频标的实现方案,突破了低相噪频率综合技术和窄带锁相环路快速捕获技术。For the requirement of coherent pilots,When SMA ground multi-beam forming FDM transformation, an implementation scheme for high-precision tracking and restoration of out-of-band targets for on-board spread spectrum telemetry signals was studied,and the low phase noise frequency synthesis technique and narrow-band locked loop fast capture technology.were broken through.

关 键 词：频标同步 快速捕获与跟踪技术
