| Abstract: | Simulating array signal of sonar system plays very important roles in sonar design and sonar operator training, especially in digital sonar. An algorithm is presented in this paper for these purposes, in which the signal is simulated by addressing a standard signal table, and the pseudo-random white noise is generated by using the sum modulo 1 that can be realized with high speed DSP chips. The algorithm is calculated on a parallel pipeline architecture hardware platform which consists of two TMS320C25 chips, and several peripheral modules. The simulation of the system on computer and the hardware realization prove that the design is right and efficient. |
