基于共轭FRFT模对消的反辐射导弹检测
ARM Detection Based on Conjugated FRFT
摘要
Abstract
In the paper, the amplitude characteristics of ARM echo signal and ARM carrier echo and their conjugate signals are analyzed. On the basis, a detection method based on conjugated FRFT for ARM is proposed. The ARM echo signal has good energy congregate at the best angle, but its conjugate signal have no energy congregate at the angle. ARM carrier echo and its conjugate signal has symmetrical characteristic about the origin in FRFT domain. The difference between the two FRFT models is used to weaken partly ARM carrier echo and increase the detect probability. Experiment using IPIX data shows that the proposed method has good detection probability in low SCR.关键词
