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.

How Can a Cognitive Radar Mask its Cognition? [PDF]
ICASSP 2022 - 2022 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2022 We study how a cognitive radar can mask (hide) its cognitive ability from an adversarial jamming device. Specifically, if the radar optimally adapts its waveform based on adversarial target maneuvers (probes), how should the radar choose its waveform parameters (response) so that its utility function cannot be recovered by the adversary.

Science & technology trends in cognitive radar concept
Системи обробки інформації, 2021 Currently, human operators provide cognition in a radar system. However, advances in the “digitization” of radar front-ends, including digital arbitrary waveform generators (AWG) and advanced high performance embedded computing (HPEC) make it possible to

Cognitive radar: A way forward [PDF]
2011 IEEE RadarCon (RADAR), 2011 The desire to autonomously anticipate, find, fix, track, target, engage, and assess, anything, anytime, anywhere (AF2T2EA4) in spectrally dense environments will require changes to how we build, modify, and deploy radar and radio frequency systems. These spectrally dense environments coupled with the twenty-first century threat are already causing ...
