摘　　要：提出一种基于模数混合信道化宽带处理和实时流水处理技术的超宽带高速跳频信号实时非合作接收机结构,采用基于无盲区数字信道化、多通道数据融合的频率跳变时刻估计算法和针对差分相移键控(SDPSK)信号的实时解调方法,解决了超宽带高速跳频信号的实时解跳和解调难题。为进一步验证所提出结构和算法的有效性,设计并实现了一种针对2 GHz,20 000 Hop/s跳频信号的超宽带高速跳频实时非合作接收机。测试结果表明:该接收机能实现对超宽带高速跳频信号的实时解跳和解调。An ultra wideband high-speed frequency hopping non-cooperative receiver based on analog-digital mixed channelization and continuous real-time processing technique is developed for real-time receiving of ultra wideband high-speed frequency hopping signals. An epoch timing estimation method based on non-blind zone channelization and muhi-channel data fusion is proposed, and the real-time demodulation method for Symmetrical Differential Phase Shift Keying（SDPSK） signal is also discussed in this paper. To validate the proposed method and algorithm, a 2 GHz 20 000 Hop/s ultra wideband high-speed frequency hopping non-cooperative receiver is implemented, the experimental results show that the receiver developed can intercept and analyze ultra wideband high-speed frequency hopping signals in real time effectively.
