EM spectrum electromagnetic spectrum. The range of frequencies from zero to infinity where energy is transferred by electric and magnetic waves. EM waves at the lower end of this spectrum (low-frequency navigation aids and AM and shortwave radio services) are refracted back to earth by the ionosphere to frequencies as high as 50 MHz. At frequencies above 50 MHz, propagation is generally limited to LOS. These frequencies are used by TV, FM radio, and land-mobile and point-to-point communication services. They extend on to parts of the EM spectrum generally termed as radar, IR, visible light, UV light, and cosmic rays.

radar A device that uses EM waves to provide information on the range, the azimuth, or the elevation of objects.

radio detection The detection of a radio's presence by intercepting its signals without precise determination of its position.
radio direction-finding The act of determining the azimuth to a radio transmitter, from a specific location, using signal-detecting equipment.
radio fix The location of a radio transmitter determined by simultaneously using two direction-finding devices stationed at different locations and plotting the results on a map. The intersection of the two azimuths indicates the transmitter's location.
radio range-finding The act of determining the distance to a radio transmitter. This technique involves using electronic equipment to intercept and measure a transmitter's emissions and then translating this information into a distance.

smoke generator A machine that produces large volumes of smoke to support hasty or deliberate operations for screening, protecting, and/or sustaining airfields, ports, staging areas, and bridge crossings. Present smoke generators vaporize liquid aerosol materials such as fog oil, diesel fuel, and polyethylene glycol. These generators consist of a heat source to vaporize the liquid aerosol material and an apparatus for the production of airflow to efficiently disseminate the smoke vapor into the atmosphere where it disperses and condenses.

terrain analysis The process of examining a geographic area to determine what effects its natural and man-made features may have on military operations.
terrain mottling A camouflage technique normally used in desert terrain. It involves scarring the earth with heavy equipment to expose patches of bare ground. Equipment and supplies are placed on the bare patches to avoid detection by aerial reconnaissance.
thermal contrast The difference in radiance (as usually measured in the 8-to-14 micron band) between two features of a scene; for example, a target and its background.
thermal crossover A temporary situation, in the morning or evening, when the target and background temperatures become equal.
thermal emissivity The ratio of the emissive power of a surface to that of a black body. The emissivity is 1 for a black body and 0.9 for most natural and man-made materials. The apparent temperature of a target can be reduced by reducing its real temperature and/or lowering its emissivity. Unfortunately, as the thermal emissivity is lowered, its reflectivity in the visual portion of the spectrum increases, thus making the target more conspicuous to a visual sensor. A typical compromise is 0.7, which lowers the apparent target temperature but does not make it too shiny in the visible spectrum.
