The Transmission Waveform of Active Acoustic Homing Torpedo and ODN

There are Various torpedo transmission waveform. Classical theory of detection and parametric estimation indicates: the optimum homing receiver is related to not only sea channel but also the homing transmission waveform. Based on the relationship between the torpedo transmission waveform and ODN the paper illuminates that the transmission waveform have a great impact on the anti-reverberation effect of ODN, and the narrower pulse spectrum, the better anti-reverberation effect. At last the paper verifies the conclusion by analysing and comparing the rectanglar envelope pulse, trapezoidal envelope pulse and cosine envelope pulse.
