Abstract

The desire for passive microwave measurements of improved spatial resolution and the development of radiometer and antenna technologies have resulted in several studies to investigate large aperture radiometer systems. These systems may utilize aperture synthesis, phased array, or reflectors and phased array feeds. The in-flight calibration and thus the stability of these systems is an important consideration in any realistic study. Thus, estimates of stability and calibration requirements for these complex radiometer systems are of interest. A statistical method to characterized the stability of microwave radiometer components and subsystems which could aid in the development of numerical models to predict the stability of these radiometer systems is presented in this paper. Preliminary measurements results to demonstrate the utility and limitations of the approach are also presented.
