摘要
根据鱼雷自导过程中近/末程工作特点,提出一种宽带复杂信号设计及检测方法。利用鱼雷自导系统的宽带条件,选择具有一定水声对抗能力的多频编码脉冲,组成一种特殊的复杂信号形式,以实现准全宽带的信号发射;根据该类回波信号特点采用信号相干与非相干联合处理方法实现信号的检测。仿真结果表明了该方法的有效性。
A complex acoustic signal designed and detected method for torpedo homing in the course of its close-in attack is shown in this paper. Many frequency in broadband homing system are selected and coded in some modes making use of homing system conditions. According to echo signal characteristic, the coherence and in-coherence detection method is used in this paper. Simulation result shows its validity.
