| 摘要: |
| 针对观测过程中角度发生变化时的运动目标跟踪问题，同时考虑到常规阵列中所普遍存在的互耦效应，通过分析均匀线阵互耦矩阵的带状Toeplitz结构，提出利用在原始阵列两侧增加辅助阵元的方法补偿互耦效应对阵列响应函数的影响，并将粒子滤波技术与原始阵列经互耦补偿后的观测数据相结合，实现了阵列互耦条件下对角度变化目标的高精度方向跟踪。仿真实验验证了新方法的优良性能。 |

| Abstract: |
| The problem of direction tracking of target with varying direction based on antenna array was addressed, and the effect of mutual coupling was also considered. By exploiting the special banded Toeplitz form of the mutual coupling matrix of uniform linear array, the technique of appending assistant antennas at each side of the original array was introduced for mutual coupling compensation. After that, particle filters were used to obtain real-time direction estimates of the maneuvering targets based on the mutual coupling-compensated array output. Numerical simulations were carried out, showing the satisfying performance of the proposed method in direction tracking. |
