摘    要:通过建立北斗一号用户机接收信号模型,分析了北斗一号用户机在多种典型干扰样式下的抗干扰性能。由于干扰信号与伪随机码不相关,在北斗一号用户机接收端被扩展,通过信号通频带内的干扰信号功率大大降低,提高了相关器的输出信噪比,达到了抗干扰的目的。

关 键 词:北斗一号  扩频增益  干扰

Abstract:The BD-1 user receiver signal model is established, and the anti-jamming ability of BD-1 user receiver is analyzed in kinds of different jamming signals. The jamming signal is ex- panded in BD- 1 user receiver for uncorrelated PN code, the power of jamming signal is de- creased and SNR of correlator is increased, which achieves the purpose of anti-jamming.
Keywords:BD  gain of spread-spectrum  jamming
