A Three-Dimensional Phantom Track Generation for Radar Network Deception (January 2019)
IEEE Access, 2019 One important issue when multiple cooperating electronic combat air vehicles (ECAVs) are used to generate phantom radar tracks in a radar network is the position inaccuracy, which is the fundamental reasons for the difference between a phantom track and ...

Pointillism: Accurate 3D bounding box estimation with multi-radars [PDF]
Proceedings of the 18th Conference on Embedded Networked Sensor
Systems. Pages 340-353, 2020, 2022 Autonomous perception requires high-quality environment sensing in the form of 3D bounding boxes of dynamic objects. The primary sensors used in automotive systems are light-based cameras and LiDARs. However, they are known to fail in adverse weather conditions.

Landslides caught on seismic networks and satellite radars [PDF]
Natural Hazards and Earth System Sciences, 2021 Abstract. We present a procedure to detect landslide events by analyzing in-sequence data acquired from regional broadband seismic networks and spaceborne radar imagery. The combined used of these techniques is meant to exploit their complementary elements and mitigate their limitations when used singularly.
