Owing to the favorable ambiguity function properties and the increased deployment, mobile communications systems are useful for passive bistatic radar applications. Further, simultaneously using multiple illuminators in a multistatic configuration will improve the radar performance, providing spatial diversity and increased resolution. We compute modified Cram r-Rao lower bounds MCRLB for the target parameter delay, Doppler estimation error using universal mobile telecommunications system UMTS signals as illuminators of opportunity for passive multistatic radar systems. We consider both coherent and non-coherent processing modes. These expressions for MCRLB are an important performance metric in that they enable the selection of the optimal illuminators for estimation.
