Active sonar signals using frequency hopping group sperm sound generating method and apparatus

The present invention belongs to the field of signal detection, sonar sound source to improve the camouflage hidden capability, reducing the probability of being intercepted; so close to the transmit signal having rectangular pulse signal FH Costas superior performance; to this end, the present invention takes technical solution It is to use active sonar signal sperm group hopping sound generating apparatus and method, comprising the following steps: sTEP 1: the maximum energy of the signal pulse frequencies step: the method of generating the hopping Costas-Like sonar signals: It refers to application needs by transmission sequence between a continuous pulse group sequence or alternating transmission mode. Command interface, whale Costas sound code generator, acoustic pulse sample library memory whale, whale acoustic amplifier output, a sound sensor: generating means, including the use of frequency hopping signals active sonar sound sperm population. The present invention is mainly applied to the signal detection.
