| Abstract: | A method for acoustic signal storage and simulation of underwater target is presented in this paper. The techniques of large dynamic pulse gain control and digital waveform storage are applied. The basic principles for acoustic signal storage and target echo simulation, the control logic of system time relationship and performance analyses are introduced in this paper. its feasibility and satisfied waveform simulations have been verified through sea trail and lake trail. |
