Calculations of the radiometric temperature differences between various targets and backgrounds have been performed, and the results are presented in graphical form. In addition, an analysis is made of the effects of the varying tar get, radiometer system, and weather parameters on the detectability of targets. The data indicate that variable-area targets, such as roads and rivers especially rivers, will be detectable from very high altitudes during all weather conditions considered. Constant-area targets, such as military tanks and aircraft, will be detectable at much lower altitudes or ranges, unless the area of the target is very large.
