【摘要】 从系统功能的角度分析了连续波多普勒引信的原理和系统组成,并分解为相对独立的子系统,重点从信道的角度考虑建立部件的可以通用的数字模型,形成了无线电引信信息传递、信号处理、启动特性的数字模型,为引信对外部输入信号(干扰、抗干扰)的研究提供了仿真平台。采用MATLAB/Simulink按照从上而下、逐步细化的方法,建立了相应的仿真模型,最后对系统仿真模型进行了测试,并给出了仿真结果。更多还原

【Abstract】 Discusses the principle and form of continuous wave doppler fuze in the point of view of system function, and reduces it into comparatively unattached subsystem. Construct the mathematical model which can be used generally from a point of view of signal tunnel, and which is a platform for analysis the fuze’s response to the external input (jamming and noise) with radio fuze signal transferring, processing and startup characteristics.Building this model is accomplished on platform of the MATLAB/Simulink by the way of up-to-down and pace-fine, test on this simulation platform is held and the simulation result is presented.更多还原
