Dynamic multi-radar cooperative detection and tracking method and system based on target resolution for unmanned aerial vehicle cluster

Abstract

The application discloses a kind of dynamic unmanned aerial vehicle cluster multi-radar cooperative detection tracking methods and systems based on target resolution, specifically: the observation scene of multiple radars to unmanned aerial vehicle cluster is constructed;Multiple radar observation scene is observed group division and geometric relation is solved, cluster target electromagnetic scattering characteristic calculation and multi-radar time-varying scattering center modeling are carried out;Multiple radar signal level echo model is constructed, echo data is beamformed, range-azimuth spectrum and range-elevation spectrum are constructed, realize cluster target resolution and parameter output;Single-station dynamic measurement data of each radar is generated, spatial registration and fusion preprocessing of multi-station measurement data are completed, and cooperative accurate perception result is output.The system includes four modules of multiple radar observation scene modeling, cluster target characteristic calculation, dense target resolution detection, multi-radar cooperative perception tracking.The application realizes the high-precision, multi-dimensional radar perception of unmanned aerial vehicle cluster, optimizes detection performance, and improves tracking quality.
