摘　　要：针对卫星通信系统中对固定中频频段进行在线频谱监测的需求,提出一种中频直接采样,并进行数字信号处理的方法。该设计采用多相抽取滤波、信道划分等多种优化处理方法,克服了数据速率过高的瓶颈,最大限度简化了设计,减少了费用。In view of demanding a regular intermediate frequency spectrum analysis in satellite communication system, a intermediate frequency direct sampling and digital signal processing method is put forward. Poly-phase filtering and channel dividing optimizing method are adopted in the design, the bottleneck of over-fast in data rate is overcome, and the design is best simplified and the cost is mostly reduced.
