An air-ground cooperative three-dimensional electromagnetic spectrum mapping device and method

Abstract

This invention discloses an air-ground collaborative stereoscopic electromagnetic spectrum mapping device and method. The device includes an airborne platform, a vehicle-mounted platform, and a ground station. First, it receives mapping parameters, plans a collaborative acquisition path between the airborne and ground platforms, and simultaneously collects, frames, and stores spectrum and spatiotemporal information. Second, after compensating the spectrum data from each platform, it performs three-dimensional fusion of air, time, and frequency. Based on the platform's real-time location and the fused data, it delineates dynamically complete areas and completes missing grids using an online optimization algorithm with a forgetting factor. Finally, it calculates the map coverage in real time; if the coverage exceeds a threshold, it replans the supplementary measurement path until a complete stereoscopic spectrum map is generated. This invention combines the advantages of airborne and ground platforms to achieve high-precision three-dimensional spectrum perception in large-area, complex scenes, improving completion accuracy and real-time performance.
