海面干扰信号的研究及仿真

Research and Simulation of the Sea Clutter Signal

海面对引信的干扰很大 ,易造成引信弹道早炸。为了加强引信的抗干扰性 ,该文研究了海面干扰信号的平均功率 ,海面有效反射系数的特性 ,海面干扰信号的幅度分布特性和功率谱特性。根据干扰信号的分布特性 ,采用随机信号产生理论 ,仿真出不同海情时的海面干扰信号 ,可用来检验引信的抗干扰性。

Fuze is greatly jammed by sea clutter and is likely to be exploded ahead. To strengthen fuze ability of the anti jamming,this paper studies the average power of sea clutter and effective reflection coefficient of sea clutter, and analyzes the amplitude distribution and frequency distribution of sea clutter signal. According to the distribution of sea clutter,this paper adopts the system of the stochastic signal formation and simulates the sea clutter in different conditions. It is useful for detecting anti jamming property of radio fuze.
