【摘要】 研究了基于DSP的m序列相关系统,相比以前的模拟相关系统,本系统具有抗干扰能力强、系统性能好的特点。同时在分析高占空比m序列频谱特性的基础上,提出了适合于激光引信的m序列DSP相关系统解决方案。实践说明,这种系统适合于激光引信,并能有效提高引信的抗有源干扰能力和系统的信噪比。更多还原

【Abstract】 Discussed the DSP-based pseudo random sequence correlation system, compared to the (previous) analog one. This system has much improved performance and data processing efficiency, and also after studying the spectrum of high pulse width to zero m sequence that is applied in the laser fuze system. Constructed the real system that show good anti-passive interface performance and high signal to noise in the laser fuse system.更多还原
