悬浮式矢量边发、边收声诱饵关键技术

现代＂智能＂鱼雷的一种对抗手段是发射诱骗编码寻的信号,因此需要相应发展＂智能＂的对抗器材。边发、边收声诱饵在发射应答信号时,不关闭接收机,从而可以不受诱骗编码的欺骗,在发射强干扰的同时测量鱼雷寻的信号的频率,来控制发射频率自动跟踪鱼雷寻的频率的变化,增强声诱饵的对抗能力。对于悬浮式声诱饵,边发、边收的关键技术是抗发射声串漏、界面反射声及混响的干扰。讨论了悬浮式矢量边发、边收声诱饵的组成和信号处理方法,利用矢量传感器的零点指向性抑制强干扰,可以使诱饵发射时也能探测微弱的寻的信号,并能测量鱼雷寻的信号的频率。

The study of suspended vector receiving while emitting decoy

One of the countermeasures of modern intelligent torpedo is to emit signals with deceiving codes,so it is necessary to develop intelligent equipment against this kind of torpedoes.Receiving while emitting acoustic decoy can not be deceived by the pseudo codes,because it doesn’t turn off its receiver while emitting signals,moreover it is able to measure the frequency of the torpedo searching signal in heavy interferences so as to control the emitting frequency varying with the torpedo searching signals,which enhances the anti-capacity of decoy.The difficulty of suspended re-ceiving while emitting decoy is suppressing the interferences of emitting sound,reflected sound and reverberation from sea surface and bottom.The zero-point directivity of vector sensor can be used to suppress the above-mentioned heavy interferences,and make the decoy realize detecting faint searching signal and measuring its frequency while emitting.
