基于相位编码信号的鱼雷主动反舰声引信研究

鱼雷声引信抗干扰性能是鱼雷可靠性设计的重要指标。根据目标舰艇和海面回波的不同相位特性,提出采用相位判别的方法与相位编码信号以及脉冲压缩技术来识别目标的方法,给出了用于反舰声引信信号处理框图,并进行了仿真计算。仿真结果证明了文中提出方法的可行性和正确性。

Research on torpedo anti-ship active fuze based on phase-coded signal

The anti-jamming capability of torpedo active ultrasonic fuze is an important reliability index in torpedo design. According to the difference of the phase from the object and the surface,a method of distinguishing objects was proposed by the phase of echo.At the same time,the phase co-ding signal and pulse compressing technology was used.An anti-ship ultrasonic fuze signal processing scheme was given.The simulation result proves that the method is feasible and correct.The anti-jamming capability of the ultrasonic fuze system is improved by this method.
