摘要
本文对低信噪比直接序列扩频（DS／SS）信号的检测提出了设计方案和算法。提出的频域自适应抑制窄带信号过程中对存在的DS／SS信号的损失相对较小，提出的数字滑动窗积分自相关算法能大大缩短检测时间，并结合实验系统给出了检测概率的统计性能。
One detection design block diagram and algorithms for low S/N DS/SS signal are presented in this paper. The algorithms include frequency-area adaptive narrow-band signal suppressive algorithm (FANSA) and degital moving window autocorrelation algorithm (DMWAA). FANSA 1osses a little of DS/SS iganalrelatively while it suppresses narrow-band signal, DMWAA improves the detective speed rapidly. The detection performance is presented in the end of this paper.
