Envelope (radar)

Radar envelope is a critical Measure of Performance (MOP) identified in the Test and Evaluation Master Plan (TEMP). This is the volume of space where a radar system is required to reliably detect an object with a specific size and speed. This is one of the requirements that must be evaluated as part of the acceptance testing process.

This is the volume of space where a radar system is required to reliably detect an object with a specific size and speed. This is one of the requirements that must be evaluated as part of the acceptance testing process. Radar systems have natural deficiencies because the laws of physics create performance constraints that cannot be altered. The ambiguity function associated with pulse compression and scalloping associated with moving target indication are two examples. Complete coverage requires radar at multiple locations and multiple different kinds of radar.
