Bi- and multistatic radar are expected to benefit from their separation of transmitter and receiver that denies receiver recognition by ARM, favours covered operation by their silent receivers, has higher detection possibilities of stealthy objects and is less vulnerable to jamming. The requirements of synchronization in a separated transmitter-receiver system are discussed. The processing in bistatic radar must include the knowledge of geometry dependencies that exist for bistatic radar in range, Doppler and SN ratio. Different track profiles relative to bistatic radar orientation and their range-Doppler relationships are presented together with examples from the processing in different types of bi- and multistatic radar. The extraction of target parameters, such as position, velocity and heading could require the combination of data as a function of time andor contribution from several systems. A discussion of tracking in bi- and multistatic radar is included to the end that uses simulated input to estimate parameters with comparison of different methods of estimating measurement uncertainty and the use of bistatic or multistatic radar input data.
