This repository provides code and workflows to test several state-of-the-art vehicle detection deep learning algorithms —including YOLOX, SalsaNext, RandLA-Net, and VoxelRCNN— on a Flash Lidar dataset ...
The discovery of the rotational Doppler effect (RDE) has opened new opportunities for detecting parameters of rotating targets. In recent years, the physical mechanisms underlying this effect have ...
We propose a technique for extracting the Doppler shift and its rate from OneWeb’s Ku-band user downlink signals and demonstrate its suitability for opportunistic positioning. Since the downlink ...
Forbes contributors publish independent expert analyses and insights. Jim Gorzelany is a veteran automotive journalist. Like roll-up windows and cigarette lighters, manual transmissions are a dying ...
Outside every National Weather Service (NWS) office around the U.S. stands what looks like an enormous white soccer ball, perched atop metal scaffolding several stories high. These somewhat plain ...
In May 2024, Disney CEO Bob Iger announced Marvel would be shifting its focus to quality over quantity. Instead of four movies and TV shows per year, Marvel would scale back and only release two to ...
Abstract: Doppler shift has significant implications in Low Earth Orbit (LEO) constellations due to the rapid relative movement of satellites. This letter presents a novel approach based on stochastic ...
