Abstract

A multispectral passive sensor may be used to measure the range to an object, provided that the light emitted is described by a black (gray) body distribution, and atmospheric attenuation coefficients between receiver and target are known. With additional time evolution passive measurements, it may be possible to estimate target range and radial velocity with more limited amount of information on atmospheric channel properties. In this paper we establish limits on the accuracy of range and velocity estimation using selected statistical models and LOWTRAN VII generated atmospheric scenarios. The results presented and the methodology developed are important in determination of the limits of infrared sensing and for a critical evaluation of possible advantage of hybrid passive-active or passive only sensors in various scenarios.
