Paper Abstract

Pixel-size effects on the probability of detection and on measurement extraction accuracy (the position measurement noise variance) for point sources in the focal plane (FP) of an optical sensor are analyzed from a general target tracking perspective. The analysis uses the point spread function of the optical sensor, which causes distant targets | point sources | to appear as a spatially extended pattern in the FP. Measurement extraction, both via Maximum Likelihood Estimation (MLE) and pixel detection centroiding is examined. The impact of pixel size, target strength (SNR) and target motion uncertainty (“maneuvering index") on tracking accuracy are quantified theoretically and verified by simulations.
