本文介绍了一种主动声纳波形仿真系统。在算法上利用了主动声纳波形的窄带性质,先在较低采样率下完成回波、混响、本舰噪声、海洋噪声复包络的运算,然后再经调制运算把复包络调制成高频波形,有效降低了对计算速度的要求。在结构上采用两级TMS32020配置,分别实现波形复包络运算和调制运算,充分发挥了硬件的处理能力。运行结果表明,该系统的仿真逼真性和工作可靠性都是令人满意的。 This article describes a proactive sonar waveform simulation system. The algorithm takes advantage of the narrow-band nature of the active sonar waveform. The echo, reverb, ship’s noise and ocean noise complex envelope are first computed at a lower sampling rate, and then the complex envelope is modulated High-frequency waveform, effectively reducing the computational speed requirements. In the structure of two TMS32020 configuration, respectively, the waveform complex envelope operation and modulation operations, give full play to the hardware processing power. The running results show that the system simulation of realism and reliability are satisfactory.
