根据应急任务的观测需求,确定了天基传感器在应急任务时的观测组合问题模型。从允许按需调整观测需求要素的权值角度出发,提出了一种面向应急任务的天基传感器观测组合评定方法,实现了对天基传感器观测组合的定量评定。实验结果表明,此方法用于天基传感器观测组合方案的优势程度选取是可行的。

Space-based satellite sensors are the important data sources needed to be planned in an emergency mission.Usually,one single space-based satellite sensor cannot fully provide the observation information.According to the dynamic and complex observation needs of emergency task,the program of multiple space-based satellite sensors＇ observation combination should be generated.In this article,we identify the problem model for a combination of space-based satellite observations based on the needs of a emergency tasks.By setting the weights of the observation requirement factors on-demand,we propose an emergency mission oriented evaluation method for a combination of space-based satellite sensors＇ observations that can realize a reasonable assessment for selecting the sensors combinations.Experimental results show that the use of this proposed method is a feasible solution for evaluating the program of combinations of observations from different space-based sensors.
