摘要 针对遥感监测信息的效用评估问题,提出了一种态势感知能力定量分析的新方法。首先利用NIIRS等级尺度和GIQE模型建立了遥感图像与地面目标检测率之间的联系,由此得到这些目标在监视区域出现的概率分布。然后,以地面目标在监视区域的实际分布表示使用者信息需求,并利用信息理论中的Kullback Leibler距离来度量不确定性分布和信息需求之间的差异,从而得到不同遥感侦察与监视系统态势感知能力曲线,给出了传输处理时延对态势感知能力曲线的影响。 <Abstrcat>A new way related to the performance analysis of Surveillance and Reconnaissance Systems is proposed to evaluate the situation awareness. At first, NIIRS and GIQE are used to find the relationship between the remote images and targets' detection probability, so the probability distribution of the targets in the surveillance area is gotten. Secondly, considering the real distribution of the targets as the users' need for information, we use Kullback-Leibler distance in the information theory to measure the difference between the probability distribution of the targets and the users' need for information. Finally, a situation awareness curve of different S&R systems is derived and the impact analysis of the transmission and processing delay on the curve follows.
