Mission Analysis for Synthetic Aperture Radar Satellite System

摘要

摘要: 系統(tǒng)地總結(jié)了國內(nèi)外合成孔徑雷達(SAR)衛(wèi)星的發(fā)展現(xiàn)狀及趨勢，提出了大視角雙側(cè)視SAR衛(wèi)星的新概念。針對SAR衛(wèi)星有效載荷的特點，從用戶需求分析和關鍵約束條件入手，研究了衛(wèi)星軌道設計與覆蓋性能分析方法，總結(jié)了雷達波位參數(shù)設計和系統(tǒng)性能分析方法，提出了SAR衛(wèi)星系統(tǒng)星地一體化任務分析方法。通過計算機仿真，對大視角雙側(cè)視SAR衛(wèi)星概念進行了初步可行性分析。

Abstract: The development of Synthetic Aperture Radar (SAR) satellite is summarized. A new concept of high-elevation angle, double-side looking SAR satellite system is introduced According to the analysis of the users requirements and the key technical restriction, the performance of radar coverage is analyzed with the optimal orbital elements design for SAR satellite, and the beam position parameters design and system performance analysis are implemented. The space-ground integration approach of mission analysis for SAR satellite is proposed, basing on the characteristics of SAR payload. The computer simulation results are presented, which illustrates the validation of the new approach and the feasibility of high-elevation angle, double-side looking SAR satellite concept.
