一种时域降维多帧处理的Radon域弱目标检测
Novel weak target detection technique based on time-dimension reduced multiple frame detection in the Radon domain
摘要
Abstract
Low-altitude slow-moving weak target detection in the heavy clutter is a challenging problem for low resolution radar.This paper proposes a time-dimension reduced multiple frame detection algorithm in the Radon domain to solve it.In our framework, adaptive moving target indication (AMTI) and the order statistic constant false alarm rate filter (OS-CFAR) are utilized to suppress the clutter primarily.After resampling and smoothing the combined time-range profiles in the time direction, the Radon transform is applied to this set of new time-range profiles.Then target detection is converted into a problem of feature extraction in the Radon domain, and the moving target can be figured out by two thresholds from the clutter in the parameter domain.Since the differences of skewing angles between the slow-moving targets and clutter in the Radon domain are amplified by time-dimension reduction operator, we can both detect the target and estimate its velocity.Real data demonstrate the effectiveness of the proposed algorithm.关键词
