Radar-Based Vital Signs Detection For In-Cabin Applications
By Cadence - 10 Oct, 2024 - Comments: 0

Radars have been at the forefront of the automotive industry for some time now. They play an integral part in advanced driver assistance systems (ADAS) and aid in applications such as adaptive cruise control, collision mitigation, blind spot detection, lane change assist, and many other applications. In-cabin sensing is an emerging area in the automotive industry, and radars play an integral... » read more

Photonics Could Reduce The Cost Of Lidar
By Karen Heyman - 05 Sep, 2024 - Comments: 0

Using light to move data over shorter distances is becoming more common, both because there is much more data to move around and because photons are faster and cooler than electrons. Using optical fiber for mission-critical communication is already well established. It has been the preferred PHY for long-haul communications for decades because it doesn’t suffer from the attenuation losses ... » read more

Research Bits: Feb. 21
By Susan Rambo - 21 Feb, 2023 - Comments: 0

High-quality ‘chirps’ for automotive, industrial mmWave radar Imec demonstrated a low-power phase-locked loop (PLL) that generates high-quality frequency-modulated continuous-wave (FMCW) signals for mmWave radar, which can be used in short-range automotive and industrial radar applications. The FMCW radars popular in healthcare, automotive, and industrial send out sinusoidal waves that get... » read more

Fixed-Point And Floating-Point FMCW Radar Signal Processing With Tensilica DSPs
By Cadence - 25 Jan, 2023 - Comments: 0

Automotive Advanced Driver Assistance Systems (ADAS) applications are increasingly demanding radar modules with better capability and performance. These applications require sophisticated radar processing algorithms and powerful Digital Signal Processors (DSPs) to run them. Because these embedded systems have limited power and cost budgets, the DSP’s Instruction Set Architecture (ISA) needs t... » read more

Automotive Lidar Technologies Battle It Out
By Bryon Moyer - 05 Aug, 2021 - Comments: 1

Lidar is likely to be added to the list of sensors that future cars will use to help with navigation and safety, but most likely it won't be the large rotating mirror assembly on the top of vehicles. Newer solid-state radar technologies are being researched and developed, although it’s not yet clear which of these will win. “The benefits of lidar technology are well known dating back to ... » read more

Here Comes High-Res Car Radar
By Mark LaPedus - 20 Nov, 2017 - Comments: 1

A dozen or so startups are developing high-resolution radar chips that use various modulation schemes and processes, such as CMOS, FD-SOI and even metamaterials. In theory, high-resolution radar could boost the capabilities of today’s radar for cars, as well as eliminate the need for a separate LiDAR system. But the technology is still in the research stage and has yet to be proven commerc... » read more
