A multistatic radar uses two or more receiving sites with overlapping coverage and combines target data coherently or noncoherently at a central location. Examples of noncoherent data combining are SPASUR and the MMS although for both systems, each transmitting-receiving pair operates coherently; that is, each receiver establishes phase coherence with the transmitter and coherently processes the bistatic echo. Examples of coherent data combining are thinned, random, and distorted arrays, the Radio Camera, and interferometers, such as SPASUR when it operates in a calibration mode by cross-correlating radio star signals. Multiple transmitters can also be used, but they are not essential to the definition. When multiple transmitters are used and the transmissions from each site are coherently phased so that the multiple transmitters operate as a single transmitting array, the configuration is called a distributed array radar (DAR).
