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。
According to the observation requirements of emergency task, the model of observation combination problem of space-based sensor in emergency task is determined. In order to adjust the weight of observation requirement elements on demand, a space-based observer portfolio evaluation method for emergency tasks is proposed, which realizes the quantitative evaluation of space-based sensor observation portfolio. Experimental results show that this method is feasible for the selection of the degree of advantage of the space-based sensor observation portfolio.
