中文摘要:
      文章介绍宽带多途信号软件仿真的实现方法。通过设计一个FIR滤波器拟合指定的目标信号功率谱,产生水下目标辐射噪声信号;再结合多途海洋信道模型,得到经过多途信道传输的接收信号。该方法实现简单,可以仿真具有一定频谱特性的水下运动目标的接收信号。所产生的仿真信号可用于声纳信号处理等方面的研究工作。
英文摘要:
      This paper introduces a simple method for simulating broadband raultipath signals. Underwater target radiation noise is generated with an FIR filter that imitates the target radiation noise power spetrum, and produces broadband multipath signals using a multpath channel. Simulation signals produced by this software can be used in research such as passive sonar signal processing, etc.
