探雷声纳背景图像仿真的快速实现

摘要

A quick realization method of background image simulation for mine-detecting sonar exercising is proposed. In this method, when the sonar beams illuminate the 3-D waving seabed, the randomicity of the grazing angle is embodied in the coefficients of the sea bottom sediment, and all kinds of background images can be simulated realistically. The calculation volume of sonar image simulation is smaller than the smallest repetition period of mine-detecting sonar, that fulfills the need of mine-detecting sonar simulation exercising.%为了真实地模拟海底背景,提出了一种适用于探雷声纳模拟训练的背景图像仿真快速实现方法,该方法将声波照射三维起伏海底掠射角的随机性体现在海底底质的比例系数中,可以逼真地仿真出各种起伏海底的背景图像,仿真计算时间小于探雷声纳最小重复周期,满足了探雷声纳模拟训练的需要.
