Automated Ground Truth Estimation For Automotive Radar Tracking Applications With Portable GNSS And IMU Devices [PDF]
Published in Proceedings of 20th International Radar Symposium
(IRS), Ulm, Germany, June 2019, 2019 Baseline generation for tracking applications is a difficult task when working with real world radar data. Data sparsity usually only allows an indirect way of estimating the original tracks as most objects' centers are not represented in the data. This article proposes an automated way of acquiring reference trajectories by using a highly accurate ...

Computationally Efficient DOA Tracking Algorithm in Monostatic MIMO Radar with Automatic Association
International Journal of Antennas and Propagation, 2014 We consider the problem of tracking the direction of arrivals (DOA) of multiple moving targets in monostatic multiple-input multiple-output (MIMO) radar. A low-complexity DOA tracking algorithm in monostatic MIMO radar is proposed. The proposed algorithm

Interpersonal Distance Tracking with mmWave Radar and IMUs [PDF]
arXiv, 2023 Tracking interpersonal distances is essential for real-time social distancing management and {\em ex-post} contact tracing to prevent spreads of contagious diseases. Bluetooth neighbor discovery has been employed for such purposes in combating COVID-19, but does not provide satisfactory spatiotemporal resolutions. This paper presents ImmTrack, a system

Power Allocation Scheme for Multi-Static Radar to Stably Track Self-Defense Jammers
Remote SensingDue to suppression jamming by jammers, the signal-to-interference-plus-noise ratio (SINR) during tracking tasks is significantly reduced, thereby decreasing the target detection probability of radar systems.

An Improved Unscented Kalman Filter Algorithm for Radar Azimuth Mutation
International Journal of Aerospace Engineering, 2020 An improved UKF (Unscented Kalman Filter) algorithm is proposed to solve the problem of radar azimuth mutation. Since the radar azimuth angle will restart to count after each revolution of the radar, and when the aircraft just passes the abrupt angle ...
