These storms gain energy from warm water and its winds whirl in a characteristic circular motion. Tropical storms are named once winds pass 39 miles per hour, and are deemed hurricanes when winds ...

The electromagnetic waves carrying orbital angular momentum can achieve azimuthal resolution for radar imaging without relative motion. However, the difference of main-lobe direction of different ...

This paper is focus on describe a new methodology for the 2D (Azimuth and Elevation) estimation of the direction of arrival (DOA) of quasi-stationary signals, based on a Khatri-Rao (KR) subspace ...
