Paper Abstract

We discuss the current status of passive millimeter-wave radiometry as a thermal imaging technique. The major problems are poor spatial resolution and slow response time. Techniques for overcoming these difficulties are identified, including the use of aperture synthesis, multichannel receivers, correlation, and inverse transform techniques. A comparison is made with infrared imaging.
