Radar

Radar is at the heart of transformation of autonomous driving systems, with radar sensors deployed to add functionality, say Kees Gehrels and Andrew Robertson. According to research consultancy Markets and Markets, the ADAS (advanced driver assistance systems) sector is expected to grow from 334 million units in 2024 to 655 million units in 2030. As more radar sensors are added, ...

European unmanned aerial vehicle maker Tekever has signed a two-year partnership with US synthetic aperture radar maker Imsar. Under the agreement, the companies will integrate Imsar’s radars into Tekeler’s air frames. Tekever will also support Imsar’s radar development with knowledge of tactics and capabilities gathered on Ukraine’s front lines, and the agreement includes a preferred partner support package and volume ...

Texas Instruments has announced an in-cabin radar IC for vehicles that includes both RF front-end, signal processing and application processing. Revealed at CES today, AWRL6844 is a 60GHz radar made on a 40nm RF CMOS process and packaged in a 9.1 x 9.1mm BGA. Running AI algorithms locally, it is intended to provide occupancy monitoring for seat belt reminder, child ...

CSEM, the Swiss technology innovation centre is part of a consortium which is developing an AI-equipped drone to identify invasive and potentially damaging plants. Buddleia, or butterfly bushes, and Japanese knotweed can replace native plant species and others like narrow-leaved ragwort are poisonous. They can cause damage to the infrastructure, damaging railway tracks and signal installations or reduce sight lines. ...

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 ...
