TI announced a 77GHz automotive radar for automated driving today at CES in Las Vegas. Called AWR2544 and made on 45 nm RFCMOS, it is aimed, for example, at vehicles with a radar at each corner that use ‘satellite’ rather than the more locally demanding ‘edge’ vehicle architecture, according to the company. With edge architecture, the radar will perform Doppler ...

DARPA has awarded Raytheon a $15m four-year contract to increase the power density of GaN power devices in military radar. “The improved transistors will have 16 times higher output power than traditional Gallium Nitride with no increase in operating temperature,” according to the company. “Thermal management is no longer a limiting factor,” added Raytheon president Colin Whelan. Key to this ...

NXP has invested in a high-resolution distributed aperture radar software start-up, and will use its software in ICs for vehicle radar. “Distributed aperture radar offers a path to enhance the resolution of radar systems while eliminating the need for thousands of antenna channels,” according to NXP. “It coherently fuses information from multiple radar sensors on a vehicle to create a ...

Beams of electromagnetic radiation can be used to detect the rotation of distant objects if they have orbital angular momentum  – known as ‘vortex waves’. It involves exploiting a rotational form of the Doppler effect, and researchers from University of Shanghai for Science and Technology (USST) have managed to get the technique working at terahertz (THz) frequencies. “To the best ...

Rohde & Schwarz has introduced 5GHz instantaneous bandwidth front-ends for its automotive radar test set-up. “From the automotive radar perspective, a higher instantaneous bandwidth improves the distance resolution,” the company said. AREG8-81WS (monostatic – single antenna) and AREG8-81WD (bistatic – dual antenna) are for the 76 to 81GHz band and are updates on the 4GHz AREG8-81S and …D. These work ...

As the curtain has just risen on IAA Mobility 2023 in Munich on September 5, the leading Chinese provider of CMOS mmWave radar chips, Calterah, brings a most comprehensive portfolio of automotive radar SoCs at Booth A2-F31 of Mess München to the global audience. Figure 1 Visitors Showing Great Interest in Calterah mmWave Radar SoCs (please click on images to ...

Following its acquisition of Steradian Semiconductors in August, Renesas entered the automotive radar market this week when it introduced a multi-channel 76 – 81GHz transceiver at Electronica. Designed for driver assistance and Level 3 (and higher) autonomous driving, the MMIC (monolithic microwave integrated circuit) is aimed imaging radar, long-range forward radar and ‘4D’ radar, “but can also be used for ...

Vanadium carbide ‘MXene’ two dimensional materials can absorb up to 90% of electromagnetic radiation between 8.2 and 12.4GHz, according to Drexler University, out-performing more conventional materials for protecting objects against detection by X-band radar. This is not the first time MXenes have been used to block radio waves – titanium carbonates have been studied, for example – but they are ...

Infineon has created a 60GHz radar for in-vehicle occupancy detection – scanning the cabin for people and pets. “In-cabin monitoring systems detect micro-movements as well as vital signs of left-behind infants and animals and sound the alarm,” according to the company. “The radar sensor enables additional functions such as seat belt reminder and applications such as gesture sensing.” BGT60ATR24C, as ...

BAE Systems says it has successfully completed prototype tests of its Multiple Object Tracking Radar (iMOTR). This is a mobile instrumentation radar that provides radar data on multiple airborne objects, be they low flying objects, sea skimming weapons or surface craft. The tests addressed performance parameters for range, transportability, accuracy, and beacon tracking, the company said. Taking place in Fort ...
