【摘要】 本文研究了舰船辐射噪声和指定谱特征下的海洋环境噪声的数学模型,并进行计算机模拟仿真。基于嵌入式原理并以高性能 DSP(SHARC)作为算法实现平台,实时产生了多路参数可调、信噪比可调的舰船辐射噪声与海洋环境噪声信号。该模拟器具有良好的用户界面,可通过鼠标完成全部参数设置与命令选择,目前已成功地嵌入某声纳设备的实验室调机与测试,效果良好。更多还原

【Abstract】 Maths models of the radiated noise of ship and the surrounding noise of sea with specified spectrum character are studied in the article and are simulated in the computer。Based on the embedding principle,arithmetic are realized on the high performance DSP (SHARC) to generate radiated noise of ship and the surrounding noise of sea with adjustable parameters and signal-to-noise ratio in many roads in real time。Such simulator has been embedded into some Sonar Device for debugging and testing in the laboratory successfully and has got a good effect.With its good UI,The simulator can accomplish settings of all parameters and choices of commands just with mouse。更多还原
