The B-ISAR study is of current importance as it can provide a basis for distributed space-based ISAR to enable persistent co-operative space domain awareness (Co-SDA). © 2025 Elsevier B.V., All rights reserved.eninfo:eu-repo/semantics/closedAccessSpace Applications'CurrentBistaticModelling and AnalysisMonostaticNoise ImpactOscillator Phase NoisePerformancePhase Noise AnalysisPhase Noise ModelingSpace-BorneSpace-Based RadarConference Object10.23919/IRS64527.2025.110461502-s2.0-105010819912
