The kernel functions such as test signalstorage, video timing signal generation and systems control signal generation are realized by field programmable gate array(FPGA).
A method for acoustic signalstorage and simulation of underwater target is presented in this paper. The techniques of large dynamic pulse gain control and digital waveform storage are applied.
