一种基于膨胀腐蚀算法的雷达杂波感知方法OA

Aimed at the problem that traditional radar clutter perception methods mostly rely on single thresh-old segmentation and are difficult to adapt to non-uniform and non-stationary clutter scenarios,a radar clutter per-ception method based on dilation-erosion algorithm is proposed.Firstly,the clutter contour map is constructed by using the spatial-temporal distribution characteristics of clutter.Then,the initial clutter labeling is optimized through morphological closed operation to achieve refined perception of clutter regions,providing a priori basis for subsequent domain-divided clutter suppression.Simulation results show that the proposed method can effec-tively improve the continuity and physical rationality of clutter regions,and enhance the full-airspace target detec-tion performance,providing support for the optimization of radar anti-clutter algorithms.
