Multistatic radar detection - Synthesis and comparison of optimum and suboptimum receivers

Multistatic radar systems can be regarded as radars having one or more transmitting antennas, which are associated with one or more receiving antennas. The antennas are placed in separate locations. For some time monostatic radars have been predominantly used. However, in the case of military radars, techniques have to be found to make the radar systems less vulnerable to attack involving the use of antiradiation missiles (ARMs) or jamming. All forms of attack make use of the electromagnetic emissions from the radar. Multistatic radars with their passive receiving antennas are, therefore, less exposed to ARM attack than the other radars. The transmitter antenna, on the other hand, can be located in a protected position or outside tha range of action of an ARM. The present investigation is concerned with the determination of receiver structures which are capable to detect a target by processing a number of distinct radar observations obtained with the aid of various sensors.
