Paper Abstract

High sensitivity is needed for space-based infrared weak target detecting. Pixel-level Digital Integration is an effective method for promoting detection sensitivity. It’s well suited for long integration time or high irradition targets detecting. To meet the application requirements, multistage digital TDI and secondary quantification were proposeed based on pixel-level digital integration. These methods could extend integration time equivalent and restrain quantization noise. The multistage digital TDI could overcome the problem of integral time limited by the dwell time of space-based platform. The secondary quantification could reduce quantization noise to an ignorable level and therefore promote system sensitivity efficiently to photon-noise limit. On this work in progress, detecting systems with milli-kelvin level sensitivity and for infrared weak targets could be carried out.
