摘要

This letter presents a closed-form localization algorithm using the angle-of-arrival and difference time of scan time measurements from the scan-based radar (SBR). With the known radar scanning velocity, the difference time of the scan time can be converted into a subtended angle, which has linear relationship with the angle-of-arrival (AOA). The best linear unbiased estimator is applied for the optimal and reliable the AOA estimation. The weighted least square (WLS) method is used for localization of the SBR system. The presented solution is computationally efficient and statistically consistent in that the measured mean squared errors achieve the Cramer-Rao lower bounds.
