Extended Target Recognition in Cognitive Radar Networks [PDF]

open access: yesSensors, 2010
We address the problem of adaptive waveform design for extended target recognition in cognitive radar networks. A closed-loop active target recognition radar system is extended to the case of a centralized cognitive radar network, in which a generalized ...

Cognitive HF radar

open access: yesThe Journal of Engineering, 2019
Radars operating in the high-frequency (HF) band can exploit propagation modes other than line-of-sight and are hence widely employed to provide over-the-horizon surveillance and remote sensing.

Amplitude information aided waveform selection for cognitive radar tracking [PDF]

open access: yesZhihui kongzhi yu fangzhen, 2023
In order to improve the tracking performance of cognitive radar, this paper proposes a waveform selection algorithm for cognitive radar tracking assisted by amplitude information. Firstly, the framework of waveform parameter selection for cognitive radar

An intrinsically motivated learning algorithm based on Bayesian surprise for cognitive radar in autonomous vehicles

open access: yesFrontiers in Computer Science, 2022
IntroductionThis paper proposes a Bayesian surprise learning algorithm that internally motivates the cognitive radar to estimate a target's state (i.e., velocity, distance) from noisy measurements and make decisions to reduce the estimation error ...

Designing Sequences With Minimized Mean Sidelobe Level for Cognitive Radars

open access: yesIEEE 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)

open access: yesIET 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.

Online Sequential Extreme Learning Machine-Based Active Interference Activity Prediction for Cognitive Radar

open access: yesRemote Sensing, 2022
For anti-active-interference-oriented cognitive radar systems, the mismatch between the acquired and actual interference information may result in serious degradation of cognitive anti-active-interference performance. To yield more effective knowledge of

Robotic control for cognitive UWB radar [PDF]

open access: yesEncyclopedia 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.
