Abstract

Passive MMW sensing is getting more and more attention as sensors in this spectral region get better. This development requires understanding of the passive MMW target detection scenario. This scenario consists of natural background elements and targets. Understanding of the behavior of backgrounds and targets as function of environmental conditions is vital for the analysis of any future sensor performance for this spectral region. During the past year, EORD has measured the radiometric properties of natural backgrounds and several man made objects using its dual frequency 140/220 GHz radiometer. This work will describe the measurement setup and give some of the results of background and target measurements. The measurement results will be correlated to the thermal IR radiometric data and the actual contact temperatures of the objects.
