| Abstract: | The Maximum-Likelihood Estimation(MLE) algorithm for passive location of maneuvering target by single stationary station,which is based on the Direction Of Arrival(DOA) and the Time Difference Of Arrival(TDOA) information of the target,is discussed in this paper.Firstly,the maneuvering target models and the measurement equations are established.Secondly,the MLE algorithm is derived in detail.Finally,the computer simulations are made.The simulation result shows that the proposed method is practicable and effective. |
| Keywords: | passive location maneuvering target MLE |
