Millimeter-wave imaging radiometer (MIR) data processing and development of water vapor retrieval algorithms: semi-annual report under contract NAS [L Aron Chang; United States. National Aeronautics and Space Administration.]. Abstract —We have developed two passive millimeter-wave (mmW) imagers for terrestrial remote sensing: one i s an integrated imaging and spectroscopy system in the GHz range with 16 channels of MHz bandwidth each and the other is a single channel dual polarized imaging radiometer in the GHz range.

    The concept of blackbody radiation was introduced in Chapter 3. It was shown that the total power emitted by an object is a function of the temperature, and the emissivity of the material is proportional to T4 as described by the Stefan-Boltzmann law. It was also shown that if the power is measured in a region far from the emission peak, the source brightness, Bf (W/m2/Hz/ sr), is directly Author: Graham Brooker.

A millimeter wave scanner is a whole-body imaging device used for detecting objects concealed underneath a person’s clothing using a form of electromagnetic radiation.

Typical uses for this technology include detection of items for commercial loss prevention, smuggling and screening at government buildings and airport security checkpoints.

Millimeter-wave technology for application in security screening and imaging has been an area of intense research over the last few years because of the possibility to confer both acceptable spatial resolution (mm-level) and penetration of clothing and some packaging materials using non-ionizing radiation.

The radiometer design is intended to provide sufficient sensitivity for millimeter wave imaging applications with a goal of 2K noise equivalent temperature difference (NETD) at a 30 Hz frame rate.
