| Abstract: | The optimal estimate method is presented in detail for estimating the position and velocity vectors of a short range target in space with a multisensor system TR n (one transmitting sensor and n receiving sensors), and the relation between the coherent centralizing processing and decentralizing processing is discussed. After analyzing the performance of decentralization processing, the Cramer Rao lower bound (CRLB) for the estimator is given. Finally, some computational results for a special case are obtained. The results demonstrate that the system can locate a target with high accuracy. |
