NXP has combined short-range 6 – 8.5GHz UWB radar, secure ranging and angle-of-arrival processing on a single chip. Called SR250, it is for “a world that anticipates and automates, enabling a variety of new user experiences based on location, presence or motion detection across consumer or industrial IoT applications”, claimed the company. It is said to support 3D angle-of-arrival and ...

Rohde & Schwarz is looking forward to times when nations mandate radar testing as part of annual vehicle inspections. It has created RadEst, a radar target simulator intended to function in the tough world of vehicle workshops. As well as simulating targets, the unit can measure radar parameters such as EIRP (equivalent isotropic radiated power) and occupied bandwidth. “With an ...

A two-chip cascading imaging radar system has been unveiled by Calterah, based on 6T-6R mmWave radar SoCs from Andes Technology. The 22nm CMOS SoCs, which will be available from June 2024, integrate an RF module and include a quad-core CPU with a DSP and proprietary radar signal processor. Flex-Cascading allows the two SoCs to be cascaded through chip-to-chip interfaces. This ...

Kontron is aiming at military radar with is latest 6U VPX plug-in computer card, based around Intel Xeon D-2800 or D-2700 processors. Called VX6096, it includes VITA48.8 through-flow air cooling to allow operation over -40 to +55°C or, on request, -40 to +70°C (FC3) or even -40 to +85°C (CC-4). “The VITA 48.2 Type 2 conduction-cooled version can withstand card edge temperatures ...

Texas Instruments has turned to 45nm RF CMOS process to squeeze a 60GHz radar, including antenna, into an 11 x 6.7mm package only 0.8mm tall. IWRL6432AOP is an FMCW radar that works over 57 to 63.9GHz and at distances up to 25m. It includes: an RF and analogue front-end, an Arm Cortex-M3 processor to configure, control and calibrate the front-end, ...

I had no idea that it was possible to buy people-detecting radar modules for under 10 quid, but you can. There is a bunch of different models, all doing roughly the same thing in the same way: detecting moving people and other conductive objects up to a few metres away – RCWL-0516 is an example. In behaviour, they are much ...

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 ...
