A bistatic or multistatic radar that exploits non-radar transmitters of opportunity is termed a passive coherent location system or passive covert radar. Any radar which does not send active electro-magnetic pulse is known as passive radar.
A multistatic radar system. A multistatic radar system contains multiple spatially diverse monostatic radar or bistatic radar components with a shared area of coverage. An important distinction of systems based on these individual radar geometries is the added requirement for some level of data fusion to take place between component parts.
A bistatic remote sensing system would separate source 3a from sensor 3b; a multistatic system could have multiple pairs of coupled sources and sensors, or an uneven ratio of sources and sensors as long as all are correlated. It is well known that bistatic and multistatic radar are a potential means of defeating low-radar-observability aircraft.
MASINT radar sensors may be on space, sea, air, and fixed or mobile platforms. Specialized MASINT radar techniques include line-of-sight (LOS), over-the-horizon, synthetic aperture radar (SAR), inverse synthetic aperture radar (ISAR) and multistatic. It involves the active or passive collection of energy reflected from a target or object by LOS ...
The "Bistatic Radar Experiment", improvised during the mission, was designed to look for evidence of lunar water at the Moon's poles. Radio signals from the Clementine probe's transmitter were directed towards the Moon's north and south polar regions and their reflections detected by Deep Space Network receivers on Earth.
Radar astronomy is a technique of observing nearby astronomical objects by reflecting radio waves or microwaves off target objects and analyzing their reflections. Radar astronomy differs from radio astronomy in that the latter is a passive observation (i.e., receiving only) and the former an active one (transmitting and receiving).
Using radar measurements, the French Air and Space Force is able to spot satellites orbiting the Earth and determine their orbit. The GRAVES system took 15 years to develop, and became operational in November, 2005. [2] GRAVES is also a contributing system to the European Space Agency's Space Situational Awareness Programme (SSA). [3]
Bistatic radars use separated transmitters and receivers, providing indication of objects moving between the two antennas. Pages in category "Bistatic radars" The following 9 pages are in this category, out of 9 total.
