Equivalent Evaluation Method of Detection Performance of Night Vision System

With the progress of technology and the development of society, night vision technology is widely used in various fields such as aerial reconnaissance, man-portable combat, civilian outdoor scene perception and security monitoring. For direct view night vision system, the adult is usually regarded as the identification target in the assessment of detection distance. However, for the night vision system which used in fixed-wing aircraft, the targets which include airport runway, building and so on are treated as identification target in the assessment of detection distance. Due to the verification demand of long-distance detection of night vision system, this paper analysis the equivalent assessment method of detection performance, deduces the relationship of the detection distance, target size and the target characteristics parameters, proposes the principles and steps which determine the equivalent assessment parameters. Through analyzing examples, this paper calculates and verifies the feasibility of the detection performance equivalent assessment method, which can provide theoretical support for the verification of the equivalent evaluation of the detection performance of the night vision system.
