Measurement And Experiment Analysis Of Target And Background SCR

With the rapid development of information technology and increasingly high requirements for weaponry in operational environment, there are many single and independent analysis indicators for weapons systems, such as the signal to noise ratio, contrast, the target detection probability and recognition rate,but all of these can not evaluate weaponry insufficiently and comprehensively. Therefore, we need to measure the target and background images SCR and analyze the image characteristics of the target background deeply from the process of the photoelectric imaging.This article analyzes of the imaging process of a photoelectric image from the perspective of target background,that is the "target-background-interference-atmosphere-imaging sensors ".The scene images obtained from imaging sensor only contain the target and background clutter. Weapons systems most interest in the targets, so this paper can measure the SCR of target and background by studying the constitution of background clutter and what can be referred to background clutter.On this basis, this paper also measures multiple targets the background images SCR under different conditions, and the correlation between the SCR and key indicators in weapons systems (such as the detection distance, atmospheric transmittance, etc.) is analyzed, the correlation curve is obtained, and the data is fitted.
