DOAV Estimation Using L-Shaped Antenna Array Configuration

Abstract

To estimate the two-dimensional Directions of Arrival (DOA) of plane waves, a planar array is often used. The L-Shaped antenna structure provides a mechanism to estimate the 2D parameters without using a fully populated planar array. This antenna array geometry has been studied when we assume the source is stationary in the observation interval. It provides a more computationally efficient 2D DOA estimation. In this paper, we study the L-Shaped antenna array when the source is rapidly moving. In this case, not only we perform the DOA estimation but additional parameters such as angular velocities in azimuth and elevation are also estimated. In this presentation, we assume a white Gaussian background noise, and the Maximum Likelihood estimator is formulated.
