A Bayesian Surprise Approach in Designing Cognitive Radar for Autonomous Driving [PDF]

open access: yesEntropy, 2022
This article proposes the Bayesian surprise as the main methodology that drives the cognitive radar to estimate a target’s future state (i.e., velocity, distance) from noisy measurements and execute a decision to minimize the estimation error over time ...

Cognitive Radar Waveform Optimization Based on Mutual Information and Kalman filtering [PDF]

open access: yesEntropy, 2018
A new strategy to optimizing the waveforms of cognitive radar under transmitted power constraint is presented. Our scheme is to enhance the performance of target estimation by minimizing the MSE (mean-square error) of the estimates of target scattering ...

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.

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.
