Auto-calibration of Linear Array Antenna Positioning for Single Snapshot Direction of Arrival Estimation
2020
This paper presents a novel joint auto-calibration of array positioning and single snapshot direction of arrival (DOA) estimation. This technique is useful in scenarios where the array position has uncertainties which lead to degradation in DOA estimation performance as well as in an environment where the snapshot samples are limited. Our proposed joint technique presented an improved DOA estimation performance gain of 75.22% when compared to a non-calibrated estimator. Also, our results presented similar average DOA estimation performance when compared to existing state-of-the-art joint techniques without the need for high snapshot values.
