摘要
简单介绍了伪码调相与线性调频复合调制引信的工作原理。详细推导了发射信号的模糊函数,给出了三维模糊图,并借助MATLAB对复合调制信号在不同多普勒频移情况下做了仿真实验。仿真结果表明复合调制引信具有比参与复合的两种单一信号更优秀的抗干扰性能,其多普勒容限性能优于伪码调相信号。
The operating principle of complex modulation fuze using pseudorandom code phase modulation and linear frequency modulation is simply introduced. The fuzzy fuuction of the complex modulation signal is derived. The 3D ambiguity graphs are presented. The simulation of complex modulation signal under different Doppler shift condition is implemented by means of MATLAB. The results of simulation validate that complex modulation signal has more excellent anti-interference performance than either of the two signals, and the Doppler margin performance of which is better than that of pseudorandom code phase modulation signal.
