Abstract

Photon imaging system (PIS) is widely applied to astronomy observing, deep space exploration. To investigate the system performance for space application, the process that target radiance converting to photons is presented. In this processes, radiometry theory and astronomy units are used. Then a mathematical physical model for the imaging system is used to calculate the system SNR. In the model, the system dark noise and the signal enhancement process are derived as mathematical equations. The performance of the detection algorithm is also introduced to predict the PIS range performance of the probability of detection and correct localization and the probability of false alarm based on SNR. At last, the actual PIS range performance for space application is discussed and valuable data for space telescopes design and deep space exploration also are provided.
