Underwater multi-source signal generator

An underwater universal multi-source signal generator (MMSG) was proposed, which can well simulate underwater multi-source echo signals and offer a signal generating platform to the water pool experiment. The problem of how to producing multi-channel signals independently or jointly was solved, and the capabilities of controlling the parameters of the outputs and channels synchronously were achieved. The experiments show that multi moving targets' echo information, such as the DOAs, speeds, distances, can be well simulated by using this MMSG.
