Leveraging Transformer Decoder for Automotive Radar Object Detection
Changxu Zhang, Zhaoze Wang, Tai Fei +5
In this paper, we present a Transformer-based architecture for 3D radar object detection that uses a novel Transformer Decoder as the prediction head to directly regress 3D boundin…
Synthetic FMCW Radar Range Azimuth Maps Augmentation with Generative Diffusion Model
Zhaoze Wang, Changxu Zhang, Tai Fei +5
The scarcity and low diversity of well-annotated automotive radar datasets often limit the performance of deep-learning-based environmental perception. To overcome these challenges…
High-Resolution Range-Doppler Imaging from One-Bit PMCW Radar via Generative Adversarial Networks
Jingxian Wang, Moritz Kahlert, Tai Fei +3
Digital modulation schemes such as PMCW have recently attracted increasing attention as possible replacements for FMCW modulation in future automotive radar systems. A significant…
Sequential Maximum-Likelihood Estimation of Wideband Polynomial-Phase Signals on Sensor Array
Kaleb Debre, Tai Fei, Marius Pesavento
This paper presents a novel sequential estimator for the direction-of-arrival and polynomial coefficients of wideband polynomial-phase signals impinging on a sensor array. Addressi…
