Atmospheric path radiance in the infrared is an extremely important quantity in calculating system performance in certain infrared detection systems. For infrared search and track (IRST) system performance calculations, the path radiance competes with the target for precious detector well electrons. In addition, the radiance differential between the target and the path radiance defines the signal level that must be detected.

From a military point of view, it can be described as target detection at long ranges where the target image is subpixel in size. Here, the target is "unresolved.

For diffraction limited systems, acquisition range is related to the instantaneous field of view (detector limited operation) when /<1, and to the optical properties (optics limited operation) when />2.0.
