Complex point target models for multistatic radar

A mathematical and statistical model for complex point targets is proposed that may be applicable to statistical inference problems in multistatic or MIMO radar systems. Such targets are not resolved in space, but exhibit varying complex reflectivity across different bistatic view angles. The complex reflectivity can be modeled as a complex stochastic process whose index set is the set of all bistatic view angles, and the parameters of this stochastic process follow from an analysis of a target model comprising a number of ideal point scatterers randomly located within some radius of the target´s center of mass. Six different models are proposed, with different assumed distributions on the locations of the point scatterers within the target.
