摘要: 針對主星帶伴隨分布式小衛(wèi)星系統(tǒng)效能分析巾幾個關(guān)鍵問題進(jìn)行了研究。首先，根據(jù)分布式小衛(wèi)星SAR系統(tǒng)的任務(wù)需求，給出了系統(tǒng)效能評估指標(biāo)體系：結(jié)合分布式小衛(wèi)星軌道運(yùn)行特點(diǎn)，建立了系統(tǒng)能力模型：根據(jù)系統(tǒng)的工作狀態(tài)，建立了系統(tǒng)可靠性Markov模型；基于能力模型與可靠性模型，建立了主星帶伴隨分布式小衛(wèi)星SAR系統(tǒng)效能評估模型。仿真結(jié)果證明，以上模型的建立為主星帶伴隨分布式小衛(wèi)星SAR系統(tǒng)效能分析以及系統(tǒng)參數(shù)設(shè)計(jì)提供理論依據(jù)。

Abstract: To analyze several key problems about effectiveness analysis of spaceborne parasitic SAR system，firstly,an index system ofefectiveness assessment is established based on the m ission request ofdistributed SAR system；combined with orbit characteristics of distributed small satellites，the model of system capability is established；based on system working state，Markov model of system reliability is established；based on capability model and reliability model，the model of effectiveness assessment is established．The simulation results indicate the proposed models provide theoretic dependence for effectiveness analysis of spaceborne parasitic distributed SAR system. -
