Cybersecurity researchers are calling attention to a sophisticated social engineering campaign that's targeting supply chain-critical manufacturing companies with an in-memory malware dubbed MixShell.

Abstract: Radar provides information on target distance, direction, and velocity, but not directly on angular velocity. We study signal processing for estimating angular velocity directly by radar.

Abstract: A calibration method based on orbital angular momentum (OAM) is proposed for gain-phase errors in uniform circular array (UCA). The idea of the method is to construct an objective function ...
