Long-Time Hybrid Integration of Maneuvering Target Based on Sub-CPI STAP for Bistatic Space-based Early Warning Radar

The bistatic space-based early warning radar (SBEWR) needs to detect air moving targets in the presence of strong ground clutter. Meanwhile, the rapidly changing geometric relationship between the satellite and the targets, particularly for highly maneuvering targets, results in severe range cell migration and Doppler cell migration. The combined effects of clutter and target defocus significantly degrade target detection performance, especially for weak targets. To address these challenges, thi
