Research on space-based IR small target detection

Abstract

Optical early warning and detection is an important means of early warning, the photoelectric detector of which mainly uses infrared and visible light band. The targets imaging in space-based optical detector can be seen as IR small targets, thus IR (Infrared Radiation) small target detection and tracking has become an important field of optical warning and detection study. For the fluctuation of target energy, heterogeneity of imaging detector, and noise in signal processing, the target SNR (Signal Noise Ratio) in IR picture also fluctuates. The main task of this paper is to analyze the factors affecting the SNR in IR staring imaging and realize a method of multi-frame detection.
