本文提出了一种多运动目标高变形部分校准阵列的传感器定位技术。变形阵列被分成几个子阵列。第一个子阵列由预先校准的传感器组成，而其他子阵列中的传感器是未校准的。根据预校准传感器和未校准传感器之间的相位差估计传感器的位置。利用子空间正交性和多目标运动可以解决传感器位置高度变形引起的相位模糊问题。仿真结果评估了该方法的性能，并比较了Cramer-Rao边界。
In this letter, a sensor localization technique for highly deformed partially calibrated arrays with multiple moving targets is proposed. The deformed array is divided into several subarrays. The first subarray is composed of the pre-calibrated sensors, whereas the sensors in the other subarrays are uncalibrated. The positions of the sensors are estimated from the phase differences between the pre-calibrated sensors and the uncalibrated sensors. The phase ambiguities caused by the highly deformed sensor positions can be solved using the subspace orthogonality and the movement of multiple targets. Simulation results evaluate the performance of the proposed method, and the Cramer–Rao bounds are compared.
