Millimeter-wave Radars used in modern cars for cruise control and collision avoidance are usually designed to work at ranges on the order of 100 meters or so. With some engineering …read more Continue reading Machining Waveguides For 122 GHz Operation Is Delicate Work
Researchers at the University of Sydney have developed a new type of radar that can measure objects down to centimeters. The new technique uses a photonic system to generate much higher bandwidth signals, enabling radar that can detect smaller objects … Continue reading Advanced photonic radar captures images down to the centimeter scale
Back in the late 80s, our company managed to procure the complete 28 volume MIT Radiation Laboratory (Rad Lab) series, published in 1947, for the company library. To me, these …read more Continue reading Remembering the MIT Radiation Laboratory
Recent studies reported the discovery of lakes of liquid water below the polar ice caps on Mars, but others later refuted the find. Fueling the debate are two new independent studies, which have reached opposite conclusions.Continue ReadingCategory: Sp… Continue reading Two new studies join debate over presence of liquid water lake on Mars
Cannondale’s Synapse has always been a fairly well-regarded road bike, but the latest version sports a little something extra. It’s called the SmartSense system, and it’s designed to help keep riders from being struck by cars.Continue ReadingCategory: … Continue reading Cannondale’s SmartSense safety tech launches on new Synapse road bike
A few years ago astronomers announced the incredible discovery of lakes of liquid water on Mars, buried beneath the ice cap at the south pole. But sadly, a trio of new papers refutes the claim, with new experiments suggesting that the “water” signal wa… Continue reading Liquid water “lakes” on Mars may just be frozen clay, say new studies
The epicenter of the Chinese electronics scene drew a lot of attention this week as a 70-story skyscraper started wobbling in exactly the way skyscrapers shouldn’t. The 1,000-ft (305-m) SEG …read more Continue reading Hackaday Links: May 23, 2021
On July 4th, 1976, as Americans celebrated the country’s bicentennial with beer and bottle rockets, a strong signal began disrupting shortwave, maritime, aeronautical, and telecommunications signals all over the world. …read more Continue reading The Russian Woodpecker: Official Bird of the Cold War Nests in Giant Antenna
