A method and apparatus based on the exploitation of quantum effects related to stimulated emission for detecting the presence of aircraft or missile exhaust plumes in the atmosphere. In the preferred embodiment, the present invention is directed toward detecting electromagnetic radiation due to the presence of chemical compounds existing in the exhaust plume which occur in areas of the spectrum not normally interrogated; that is, in the regions of 0.2-200 microns and 1 KHz-1000 GHz.

[ We claim:] [1.] A method for detecting the presence of aircraft or missile plumes in the atmosphere using stimulated emission, comprising the steps of:obtaining a chemical analysis of the chemical composition of a first exhaust plume;first detecting stimulated emission produced by said first exhaust plume;first producing a first data signal proportionate to said stimulated emission produced by said first exhaust plume;recording said first data signal;second detecting stimulated emission in the atmosphere;second producing a second data signal proportionate to said stimulated emission detected in said atmosphere; andcomparing said second data signal to said recorded first data signal to obtain an indication of the presence of a second exhaust plume.
