Millimeter-Wave Radiometric Utility Study
Abstract
The purpose of this task is two-fold. The general purpose is to provide an introductory discussion of passive millimeter-wave radiometry and its value to remote sensing, illustrated by examples of imagery. The imagery of relatively high resolution has been acquired at various frequencies from aircraft, and the imagery of lower resolution (12.5 km), also important in intelligence gathering, has been acquired by the 85.5 GHz channel of the DMSP- SSM/I (F8). Examples of military, man-made, and environmental targets illustrate the all-weather capability of passive millimeter-wave systems and the types of signatures received. The meteorological subjects-particularly the millimeter- wave characteristics of tropical cyclones, frontal systems, and clouds-have become the basis of additional environmental work at NRL (to be published later under separate cover). The more specific purpose in this report is to study the utility of passive millimeter-wave imaging from space enhanced with systems that provide surface resolutions of 100-400 m and operate at 90 GHz. The utility, including limitations, of this system for target detection, surveillance, and environmental monitoring is discussed
