Cognitive node selection and assignment algorithms for weighted cooperative sensing in radar systems [PDF]
, 2009 For the radar spectrum to be shared efficiently a good sensing capability within a secondary cognitive communication system is required. In this paper, the swept radar's rotation mechanism is explored to improve the sensing performance.

The Waggle Dance as an Intended Flight: A Cognitive Perspective [PDF]
, 2019 The notion of the waggle dance simulating a flight towards a goal in a walking pattern has been proposed in the context of evolutionary considerations. Behavioral components, like its arousing effect on the social community, the attention of hive mates ...

Cooperative Radar and Communications Signaling: The Estimation and Information Theory Odd Couple [PDF]
, 2014 We investigate cooperative radar and communications signaling. While each system typically considers the other system a source of interference, by considering the radar and communications operations to be a single joint system, the performance of both ...

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.
