Entanglement-Assisted Joint Monostatic-Bistatic Radars

open access: yesEntropy, 2022
With the help of entanglement, we can build quantum sensors with sensitivity better than that of classical sensors. In this paper we propose an entanglement assisted (EA) joint monostatic-bistatic quantum radar scheme, which significantly outperforms ...

Microwave Photonic Radars

open access: yesJournal of Lightwave Technology, 2020
As the only method for all-weather, all-time and long-distance target detection and recognition, radar has been intensively studied since it was invented, and is considered as an essential sensor for future intelligent society.

Measurement of Nonlinear RCS of Electronic Targets for Nonlinear Detection [PDF]

open access: yesJournal of Electromagnetic Engineering and Science, 2022
The conventional radar technology is based on linear detection—i.e., the same transmit and receive frequencies are used. However, with linear radars, difficulties arise when detecting electronic objects with relatively small radar cross section (RCS). To

Pointillism: accurate 3D bounding box estimation with multi-radars [PDF]

open access: yesACM International Conference on Embedded Networked Sensor Systems, 2020
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.

Potential Effects of Anthropogenic Radiofrequency Radiation on Cetaceans

open access: yesRadiation, 2023
Cetaceans are cast to shore for a large number of reasons, although sometimes it is not clear why. This paper reviews the types and causes of cetacean strandings, focusing on mass strandings that lack a direct scientific explanation.
