A literature review of millimeter and submillimeter radiation absorption and scattering in the atmosphere

The presence on the electronic battlefield of smoke, dust, aerosols and exotic gases may seriously interfere with the effectiveness of battlefield radars in the millimeter and submillimeter wavelength range that have to operate in such an environment. This report describes a literature review that was performed on the absorption and scattering processes undergone by 100 micrometers to 1 cm wavelength radiation as it propagates through the atmosphere. Recommendations are given for further experimental and theoretical work that is needed to better define the absorption by atmospheric and battlefield generated gases and the scattering and absorption by atmospheric and battlefield generated aerosols and smokes. The Appendix contains a bibliography of the unclassified unlimited and limited distribution documents included in the literature review. The bibliography of the classified documents included in the literature review is given in Volume 2 of this report.
