一种基于自适应滤波器的潜艇辐射噪声仿真方法
A Simulation Method for Submarine Radiation Noise Based on Adaptive Filter
摘要
Abstract
A simulation method for submarine radiation noise based on adaptive filter was proposed. Based on the research on the mathematical models of continuous spectrum, line spectrum and modulation spectrum of sub⁃marine radiation noise, the continuous spectrum of submarine radiation noise was simulated via inverse fourier transform based on adaptive filter using Ecs spectrum model. The simulation results was obtained after superpose⁃ing the line sepctrum signal and modulation signal. The analysis and equipment test of the simulation results showed that its naturalness was so good that the method was practical.关键词
