摘　　要：针对传统FSK-PSK信号编码方式较为固定、容易被破解截获的问题,介绍一种基于遗传算法设计实现FSK-PSK信号的方法,分析FSK-PSK信号的功率谱特性,经验证发现其对密集假目标干扰和噪声压制干扰具有很好的抑制能力。Considering that the conventional FSK-PSK signals with the fixed coding mode are easily decoded and intercepted,a new FSK-PSK signal is designed based on the genetic algorithm,and the power spectral characteristics of the FSK-PSK signal are analyzed to verify that dense false targets and noise suppression interference can be effectively rejected.

关 键 词：复合编码 伪随机 密集假目标 噪声压制
