基于分数阶模糊函数延时对消的海面运动弱目标检测
Weak Target Detection Based on Time-Delay Fractional Ambiguity in Sea Clutter
摘要
Abstract
The time shift characteristic of the signal which had double acceleration in Fractional Ambiguity was researched. Based on this characteristic. a new method based on difference of Fractional Ambiguity model for low speed moving target detection in sea clutter was proposed. Experiment using the IPIX data showed that the method had remarkably advantage in increasing the signal-clutter, FRFT peak value difference and enhancing the SCR. Setting right detection threshold, the method could detect the target better.关键词
