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...Found on http://en.wikipedia.org/wiki/Envelope_(radar)
In physics and engineering, the envelope function of a rapidly varying signal is a smooth curve outlining its extremes in amplitude. The figure illustrates a sine wave varying between an upper and a lower envelope. The envelope function may be a function of time, space, angle, or indeed of any variable. ==Example: Beating waves== If...Found on http://en.wikipedia.org/wiki/Envelope_(waves)

In audio recording software this refers to the way in which the level of a sound or signal varies over time, including alterations in a sound's amplitude, frequency and timbre. In MIDI, an instrument can be altered by manipulating the envelope which contains parameters such as attack, sustain, decay and release. (See ASDR).

changes in a sound over time, including alterations in a sound's amplitude, frequency and timbre. Used in sound synthesis to control the volume, pan, pitch or other attribute of sound over a period of time. ADSR envelopes are the most commonly used type of envelope. They are divided into several segments, Attack, Decay, Sustain and Release. The att...Found on http://www.traditionalmusic.co.uk/music%20tech%20glossary/Music%20Tech%20Gl
