Some Considerations about SWIR Gated Camera Performance by Using SNR and Detection Probability Concepts
The aim of this paper was to assess the improvement which can be add to the surveillance process which is affected by transmission and atmospheric turbulence using a Short Wave Infrared (SWIR) camera with image gating technology instead of a regular SWIR camera. As criteria for comparative analysis of their performance there were considered two key indicators: Target Detection Probability (Pdet) and image quality, materialized through Signal to Noise Ratio (SNR). The authors have considered a case study which revealed that turbulence and visibility of atmospheric influence less the operability of a SWIR system with image gating than a regular SWIR camera, especially in situations where visibility of the air is very low (less than 1 km). To analyze the behavior of the acquired image in variable atmospheric conditions there were used simulation software image as NVLaserID and SSCamIP.
