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.
Microwave radiometer A microwave radiometer (MWR) is a radiometer that measures energy emitted at sub-millimetre-to-centimetre wavelengths (at frequencies of 1–1000 GHz) known as microwaves. Microwave radiometers are very sensitive receivers designed to measure thermal electromagnetic radiation emitted by atmospheric gases. They are usually equipped with multiple receiving channels in order to derive the characteristic emission spectrum of the atmosphere or extraterrestrial objects. Microwave radiometers are utilized in a variety of environmental and engineering applications, including weather forecasting, climate monitoring, radio astronomy and radio propagation studies.
