基于CFAR和Duffing振子的FOD联合检测算法
THE COMBINED FOD DETECTION METHOD BASED ON CFAR AND DUFFING OSCILLATOR
摘要
Abstract
Foreign object debris(FOD)can do great harm to the safe operation of flying machines.Image processing to identify the target is easily affected by weather and light.Due to the scattering of airport runway,there are many false alarm signals in common CFAR detection algorithms of millimeter wave radar when the ratio of signal to clutter is relatively low.In this paper,a two-layer foreign detection algorithm combining CFAR and Duffing oscillator is proposed to solve the existing problems.The traditional clutter map CFAR was used to suppress clutter to obtain the FOD echo signal containing false alarm signal,and the frequency information corresponding to the FOD target signal or false alarm signal was extracted to generate the intrinsic signal corresponding to the Duffing oscillator.The FOD echo signal was detected to eliminate false alarm signal and the target signal was screened.Monte Carlo simulation proves the effectiveness of this algorithm.关键词
