Adaptive channel selection for DOA estimation in MIMO radarDavid Mateos-Núñez, María A. González-Huici, Renato Simoni et al.
We present adaptive strategies for antenna selection for Direction of Arrival (DoA) estimation of a far-field source using TDM MIMO radar with linear arrays. Our treatment is formulated within a general adaptive sensing framework that uses one-step ahead predictions of the Bayesian MSE using a parametric family of Weiss-Weinstein bounds that depend on previous measurements. We compare in simulations our strategy with adaptive policies that optimize the Bobrovsky- Zakaı bound and the Expected Cramér-Rao bound, and show the performance for different levels of measurement noise.
