Abstract

The invention relates to an optical remote sensing detection performance evaluation method, which belongs to the technical field of remote sensing detection; the optical remote sensing detection performance evaluation index of the present invention is obtained by comprehensively considering the contrast-limited probability and resolution-limited probability of the target and the background; wherein the contrast is limited by The limited probability is obtained based on considering the minimum resolvable contrast and the contrast factor of the target background; the resolution limited probability is obtained based on considering the Johnson criterion and the target size factor; the contrast limited probability model specifically includes the following influencing factors: noise equivalent contrast, target Contrast with background, atmospheric transmission, detection systems and platforms, display systems and the human eye. Compared with the prior art, the present invention comprehensively considers objective factors to make the evaluation result consistent with the real scene distinguished by human eyes, and is more intuitive, directly obtains the probability of discovery, identification and confirmation of the target of interest, and is easier to be accepted by users; as a This pre-evaluation system can help device system design and device selection.

Description

technical field [0001] The invention relates to a method for evaluating the performance of optical remote sensing detection, which includes a contrast-limited probability (P C ) model and the resolution-limited probability (P J ) model, especially relates to an optical remote sensing detection performance evaluation method based on Johnson criterion, noise equivalent contrast ratio (NEC) and minimum resolvable contrast ratio (MRC), which belongs to the field of remote sensing detection technology. Background technique [0002] The application fields of optical remote sensing cover military, industry, agriculture, aerospace, public security monitoring, disaster reduction and people's daily life. For optical remote sensing detection, the overall system design according to application requirements (field of view, meteorological and environmental conditions, target and background characteristics, operating distance, etc.) is the primary task of the entire photoelectric imaging ...
