成像侦察卫星识别目标能力分析

为分析成像侦察卫星的作战效能,针对光学成像侦察卫星和SAR卫星,建立了卫星识别目标的概率模型。在光学成像侦察卫星识别目标能力的模型中,引入效用函数确定由于光照、对比度、气象、卫星姿态稳定度等因素对其识别目标概率的影响。在SAR卫星识别目标能力的模型中,利用等效分辨率,并考虑了其识别目标的效用。仿真结果表明利用所建模型得到的结果与侦察实践的结果基本一致。

Capabilities of Identifying Targets of Imaging Reconnaissance Satellites

To analyze operational effectiveness of imaging reconnaissance satellites, the probability of identifying targets models were built for optical image reconnaissance satellite and SAR satellite. Utility functions were introduced to determine the effects of illumination, comparison, weather and satellite attitudes stability on the probability of identifying targets in the model of the optical image satellite. Equivalent resolution was used to build the model of the SAR satellite whose utility of identifying targets was considered. The simulation results demonstrate that the results derived from the models accord with the results derived from reconnaissance practices.
