Bistatic radar is the name given to a radar system comprising a transmitter and receiver that are separated by a distance comparable to the expected target distance.
Conversely, a radar in which the transmitter and receiver are collocated is called a monostatic radar. A system containing multiple systfm diverse monostatic radar or bistatic radar components with a shared area of coverage is called multistatic radar.
Many long-range air-to-air and surface-to-air missile systems use semi-active radar homingwhich is a form of bistatic radar. Some radar systems muotistatic have separate transmit and receive antennas, but if the angle subtended between transmitter, target and receiver the bistatic angle is close to zero, then they would still be regarded as monostatic or pseudo-monostatic.
For example, some very long range HF radar systems may have a transmitter and receiver which are separated by a few tens of kilometres for electrical isolation, but as the expected target range is of the order km, they are not considered to be truly bistatic and are referred to as pseudo-monostatic.
In some configurations, bistatic radars may be designed to operate in a fence-like configuration, detecting targets which pass between the transmitter and receiver, with the bistatic angle near degrees.
This is a special case of bistatic radar, known as a forward scatter radarafter the mechanism by which the transmitted energy is scattered by the target. In forward scatterthe scattering can be modeled using Babinet’s principle and is a potential countermeasure to stealth aircraft as the radar cross section RCS is determined solely by the silhouette of the aircraft seen by the transmitter, and is unaffected by stealth coatings or shapings.
However, target may vary from place to place location and tracking is very challenging in forward scatter radars, as the information content in measurements of range, bearing and Doppler becomes very low all these parameters tend to zero, regardless of the location of the target in the fence.
A multistatic radar system is one in which there are at least three components – for example, one receiver and two transmitters, or two receivers and one transmitter, or multiple receivers and multiple transmitters.
Bistatic radar – Wikipedia
It is a generalisation of the bistatic radar system, with one or more receivers processing returns from one or more geographically separated transmitter. 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.
Passive coherent location also known as PCL is a special type of passive radar, which exploits the transmitters of opportunity especially the commercial signals in the environment. From Wikipedia, the free encyclopedia. This article needs additional citations for verification.
