Key Points

This research aims to resolve the spatial inconsistency of radar clutter maps depending on radar platform movement.
Proposed a 3D geometric overlap ratio calculation for detection volumes.
Modeled detection areas using 3D point clouds and applied convex hull algorithms.
Analyzed overlap ratios based on movement direction, speed, detection range, and altitude.
Overlap ratio reduction is most vulnerable during forward movement but stabilizes at greater distances.
Introduced a situational awareness-based updating strategy to minimize computational load.
Enhanced resource allocation efficiency and target detection continuity in dynamic environments.

Answers are grounded in this paper and cite their sources.
