Embodiment Construction
[0044] The present invention proposes a method and processing technology for combined detection and communication signal utilizing whale sounds; The sound pulses are combined to construct a combined signal waveform; the combined signal waveform can not only be used as an active sonar signal to realize the detection of underwater targets, but also can be used as a communication signal to realize communication between underwater platforms; at the same time , the present invention provides a signal processing method matching the combined waveform described in the present invention.
[0045] The present invention is achieved like this:
[0046] Step 1: The combined detection and communication signal construction method using whale sound is as follows:
[0047] First, generate a duration of length T 1 , the starting frequency is f 1 , the termination frequency is f 2 The sonar signal s 1 (t), then, using this chirp signal s 1 (t) as a sonar signal to realize the active detect...
