Abstract: This document describes techniques and systems of a radar system with paired one-dimensional (1D) and two-dimensional (2D) antenna arrays. Even with fewer antenna elements than a traditional radar system, the paired arrays enable an example radar system to have a comparable angular resolution at a lower cost. For example, the 1D array includes antenna elements positioned in a first direction (e.g., azimuth direction) and spaced by a first distance and a second distance. The 2D array includes at least four other antenna elements positioned in the first direction and a second direction (e.g., elevation direction). The other antenna elements are spaced by a third distance in the second direction and by the sum of the first direction and the second direction in the first direction. A processor can associate, using shared angle estimates, angles in the first direction and the second direction for respective objects.

Abstract: Methods, systems, and devices for wireless communications are described. A transmitted may use a closed loop precoder for line-of-sight (LOS) multiple-input multiple-output (MIMO) communications that uses information such as distance feedback or LOS MIMO channel state feedback. A closed loop precoder may be associated with less overhead than a precoder based on full channel knowledge, such as an SVD precoder. A receiver may estimate a channel based on channel state information reference signals transmitted by the transmitter and calculate a spectral efficiency for one or more precoders of a set of precoders associated with the channel for a LOS MIMO mode. The receiver may send feedback to the transmitter that indicates a selected precoder of the set of LOS MIMO precoders based on the calculated spectral efficiencies. The transmitter may precode messages using the reported closed loop precoder.
