Super-Resolution in Automotive Pulse Radars
IEEE Journal of Selected Topics in Signal Processing, 2021 In this work we consider a mmWave pulse radar and study the problem of super-resolving the echoes produced by multiple prospective targets. We derive a novel signal model wherein an observed echo is represented in term of a conveniently-structured steering vector and its associated multi-dimensional frequency vector related to the target location; we ...

Deep Radar Waveform Design for Efficient Automotive Radar Sensing [PDF]
2020 IEEE 11th Sensor Array and Multichannel Signal Processing Workshop (SAM), 2020 In radar systems, unimodular (or constant-modulus) waveform design plays an important role in achieving better clutter/interference rejection, as well as a more accurate estimation of the target parameters. The design of such sequences has been studied widely in the last few decades, with most design algorithms requiring sophisticated a priori ...

Height-Finding for Automotive THz Radars [PDF]
IEEE Transactions on Intelligent Transportation Systems, 2019 This paper explores radar methods to measure the coordinates (distance and height) of objects on or beside a road. Knowledge of these parameters is essential in the development of autonomous or semi-autonomous cars, as well as to improve driving safety.

Automated Automotive Radar Calibration with Intelligent Vehicles
2023 31st European Signal Processing Conference (EUSIPCO), 2023 While automotive radar sensors are widely adopted and have been used for automatic cruise control and collision avoidance tasks, their application outside of vehicles is still limited. As they have the ability to resolve multiple targets in 3D space, radars can also be used for improving environment perception.

Physics‐Embedded Neural Network: A Novel Approach to Design Polymeric Materials
Advanced Science, EarlyView.Traditional black‐box models for polymer mechanics rely solely on data and lack physical interpretability. This work presents a physics‐embedded neural network (PENN) that integrates constitutive equations into machine learning. The approach ensures reliable stress predictions, provides interpretable parameters, and enables performance‐driven, inverse ...

Efficient Direct Recycling of Spent Batteries: Integrated Lithiation and Delamination
Advanced Science, EarlyView.An integrated process for the delamination and relithiation of spent cathodes, LixNi0.6Co0.2Mn0.2O2 and LixFePO4, under open‐air conditions is proposed. The transition‐metal (Ni) oxidation state in the cathode is reduced by the oxidation of diethylene glycol, facilitating relithiation. Glycol aldehyde formation induces 100% electrode delamination.
