| 摘 要： | 提出了一种方位-多普勒频差(DOA-FDOA)联合定位新算法,该算法多次应用最小二乘准则,借助目标航迹约束条件,并利用多普勒频差信息实现了对运动目标的可靠高精度定位,避免了直接求解非线性方程组。新算法的定位误差逼近CRLB,仿真结果验证了算法的可行性和有效性。

| Abstract: | In this paper,a new passive location algorithm using Direction of Arrival (DOA) and Frequency Difference of Arrival (FDOA) measurements is proposed to gain better localization accuracy. In this algorithm,the least squares criterion and track constraints are used to avoid solving nonlinear equations. The estimation accuracy of the proposed method attains the Cramer-Rao Lower Bound (CRLB) near the small error region,and the simulation results verify the validity and feasibility of this algorithm. |
