Designing Sequences With Minimized Mean Sidelobe Level for Cognitive Radars
IEEE Access, 2021 In this paper, a set of sequences is developed with a minimized mean sidelobe level (MSL). The problem is formulated for cognitive radars using the $l_{1}$ -norm, where the target cognition determines which sidelobes should be suppressed.

Moving target detection and tracking with multiplatform radar network (MRN)
IET Radar, Sonar & Navigation, 2022 A multiplatform radar network (MRN) composed of multiple transmitting and receiving facilities is advantageous over monostatic radar in moving target detection (MTD) and tracking due to the diversity gain.

Robotic control for cognitive UWB radar [PDF]
Encyclopedia with Semantic Computing and Robotic Intelligence, 2018 In the paper, we describe a trajectory planning problem for a six-DoF robotic manipulator arm that carries an ultra-wideband (UWB) radar sensor with synthetic aperture (SAR). The resolution depends on the trajectory and velocity profile of the sensor head.

THE RADAR ARCHITECTURE FOR PERSONAL COGNITIVE ASSISTANCE [PDF]
International Journal of Software Engineering and Knowledge Engineering, 2007 Current desktop environments provide weak support for carrying out complex user-oriented tasks. Although individual applications are becoming increasingly sophisticated and feature-rich, users must map their high-level goals to the low-level operational vocabulary of applications, and deal with a myriad of routine tasks (such as keeping up with email,
