The Fisher information matrix is derived given a separate target illuminator and then given a target-based isotropic signal emission. Some remarks concerning the Cramer-Rao inequality and its relationship to the estimation problem are given. Some results concerning the placement of the receivers are given and some open problems are discussed.Keywords: Cramer Rao inequality; Doppler; Estimation problem; Isotropic signal; Multi-static; Open problems; Target position; Data processing; Intelligent control; Parameter estimation; Sensor networks; Smart sensors; Fisher information matrix201010.1109/ISSNIP.2010.57067642016-02-24
