According to the underwater detection and communication integrated emission signal design and processing method provided by the invention, the characteristics of strong orthogonality and good resolution of a generalized sine frequency modulation signal are fully utilized, and a GSFM signal is used as a carrier of an integrated signal; firstly, a baseband signal product of a detection signal and a communication signal is used as an integrated signal, so that the communication signal fully utilizes the energy of the detection signal; the method comprises the following steps: firstly, receiving end signals are received, then an improved single-channel blind separation algorithm is utilized to separate the receiving end signals to obtain independent detection signals and communication signals, finally, the separated communication signals are decoded, and direct wave signal offset and target detection processing are carried out on the separated detection signals. 本发明提出了一种水下探测通信一体化发射信号设计与处理方法，充分利用广义正弦调频信号正交性强，分辨率良好
