两种基于分数阶模糊函数的运动目标检测方法
Two Methods of Moving Target Detection Based on Tractional Ambiguity Function
摘要
Abstract
In the paper,the time shift characteristic and the FRAF modules with two symmetry inverse rotation angles of the monochromatic signal,LFM signal and signal which phase has thrice-order term is studied.Two conclusions are obtained; one is that the FRAF module of time-delay monochromatic signal and time-delay LFM signal has no relationship with time delay.However the FRAF module of the signal which phase has thrice-order term is equal to the FRAF module of the time-delay signal,but has different maximum position which has relation with time-delay.The other is that the FRAF modules with two symmetry inverse rotation angles of monochromatic signal and LFM signal are same to each other.The FRAF module of the signal which phase has thrice-order term has big difference with its FRAF module with symmetry angle.Based on these characteristics,two new methods for detecting the signal which phase has thrice-order term are proposed.Experiment using the IPIX data shows the validity of the methods of the paper.关键词
