While the ST Aero MAV-1 is a low observable Unmanned Air Vehicle prototype developed between ST Aerospace and Defence Science and Technology Agency, what is designed to avoid detection using a variety of technologies that reduce reflection/emission of radar, infrared, visible light, radio-frequency (RF) spectrum, and audio?
ST Aero MAV-1 The MAV-1 (Maneuvering Air Vehicle) is a low observable Unmanned Air Vehicle prototype developed between ST Aerospace and Defence Science and Technology Agency for its swarming unmanned air vehicle research programme. The prototype was unveiled in Asian Aerospace 2004 and the first test flight was reported in 2005.
Radio receiver design Radio receiver design includes the electronic design of different components of a radio receiver which processes the radio frequency signal from an antenna in order to produce usable information such as audio. This article only concentrates on the historical configurations leading up to and including the modern superheterodyne receiver design. The complexity of a modern receiver and the possible range of circuitry and methods employed are more generally covered in electronics and communications engineering. The term "radio receiver" is understood in this article to mean any device which is intended to receive a radio signal in order to generate useful information from the signal, most notably a recreation of the so-called baseband signal (such as audio) which modulated the radio signal at the time of transmission in a communications or broadcast system.
