Bistatic radar is a radar system comprising a transmitter and receiver that are separated by a distance comparable to the expected target distance. Conversely, a conventional radar in which the transmitter and receiver are co-located is called a monostatic radar . [ 1 ]
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]
Space-based radar or spaceborne radar is a radar operating in outer space; orbiting radar is a radar in orbit and Earth orbiting radar is a radar in geocentric orbit. A number of Earth-observing satellites , such as RADARSAT , have employed synthetic aperture radar (SAR) to obtain terrain and land-cover information about the Earth .
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.
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.
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.
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.
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). Radar systems have been conducted for six decades applied to a wide range of Solar System studies. The radar transmission may either be pulsed or continuous.
