Mars may have had a lost moon – could this explain why scientists are finding evidence of ancient tidal seas on the Red Planet?

High above the rust-tinged, dusty surface of Mars, two small, misshapen and heavily cratered moons circle. Phobos, a battered, potato-shaped world roughly 22km (14 miles) across, orbits just under ...

Direction of Arrival Estimation for Linear Arrays via Taylor-Expanded Polynomial Root Finding

Abstract: We propose a direction of arrival (DOA) estimation method for linear arrays via Taylor-expanded polynomial root finding. Based on Taylor expansion, we represent the array signal as an ...

2D DOA Estimation for Multiple Parallel Sparse Linear Arrays via Recursive Roots Finding

Abstract: Multiple parallel sparse linear arrays (MPSLAs) can be strategically deployed in two-dimensional (2D) or three-dimensional (3D) space, offering a unique advantage by enabling easy conformal ...
