A terahertz wave radar based on leaky-wave coherence tomography

Researchers at Keio University and the National Institute of Information and Communications Technology (NICT) in Japan have recently introduced a new design for a terahertz wave radar based on a technique known as leaky-wave coherence tomography. Their paper, published in Nature Electronics, could help to solve some of the limitations of existing wave radar.

The use of , particularly millimeter-wave radar, has increased significantly over the past few years, particularly in the development of smart and self-driving vehicles. The distance and angular resolutions of radar are typically limited by their bandwidth and wavelength, respectively.

Terahertz waves, which have higher frequencies and shorter wavelengths than millimeter waves, allow for the development of radar systems with a smaller footprint and higher resolution. As wavelengths become shorter, however, the attenuation resulting from wave diffraction rapidly increases.

Tesla vehicles confirmed to be used in Elon Musk’s Boring Company Las Vegas Loop, watch breakthrough in real time

Tesla vehicles are now confirmed to be used in Elon Musk’s Boring Company Loop project to create an electric people mover at Las Vegas’ massive convention center.

You can watch them break through the first tunnel in real time.

Last year, we reported on the Boring Company announcing a new proposed “Loop” system of tunnels for approval in Las Vegas.

Step Aside 2021 Escalade, Cadillac’s Next Big Reveal Now Official

Cadillac is fully aware it needs to continue launching new vehicles that are not only relevant for the times but also offer something new. That something is — big surprise — electrification. At the moment, GM’s luxury brand does not sell an EV and its only hybrid model, the Cadillac CT6 Hybrid, is about to be discontinued. Eventually, the just-revealed 2021 Cadillac Escalade will likely offer a plug-in hybrid variant and, perhaps, an all-electric one as well. Thing is, Cadillac can’t wait that long for an Escalade EV, but it turns out an alternative is coming very soon.

GM President Mark Reuss announced last week at the automaker’s Capital Markets Day presentation the brand’s first-ever EV will debut this April. And yes, it will be a crossover, a fact that was announced a year ago at the Detroit Auto Show. Oddly, Cadillac did not preview this vehicle with a concept in the Motor City.

Eyes to the skies: Rocket launch to be visible in DC region

NASA Wallops Flight Facility is scheduled to launch a rocket tonight that will be visible to the DMV as it climbs into the sunset sky.

The facility hopes to launch the 13th Northrop Grumman resupply mission to the International Space Station (ISS) at 5:39 p.m. near sunset. The Cygnus cargo ship (spacecraft) is the S.S. Robert H. Lawrence, named for the first ever African American selected as an astronaut.

The launch and mission will be carried live by NASA.

Congress Proposes Nationwide Network of Electric Car Chargers

Representatives Alexandria Ocasio-Cortez and Andy Levin have introduced a new bill that would build a national infrastructure for electric vehicles.

The EV Freedom Act would allocate the resources for the U.S. to build a nationwide network of electric vehicle chargers within five years, Reuters reports. That would alleviate a major hurdle to widespread electric car adoption, making it far easier for the population to transition away from gas power.

Virgin Orbit nearing first launch

MOUNTAIN VIEW, Calif. — Virgin Orbit says it is weeks away from the first orbital launch of its LauncherOne rocket as the company makes plans to move quickly into operations if that flight is successful.

The company said in a series of tweets Jan. 31 that is in final preparations for its test launch, with the LauncherOne rocket attached to its Boeing 747 aircraft for a final series of tests and dress rehearsals at the Mojave Air and Space Port in California. That includes a captive carry flight, where the plane will take off with the rocket attached for the entire flight.

The company didn’t disclose when that launch would take place beyond that it was “really close” to being ready for the flight. Dan Hart, chief executive of Virgin Orbit, said that launch would take place in the “coming weeks” during a panel discussion at the SmallSat Symposium here Feb. 4.
