Research Bits: Feb. 21

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

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

Radar For Automotive: Basics Of FMCW Radar

Radar (acronym for Radio Detection and Ranging) uses radio waves to detect objects in the environment. It allows determining the distance (known as range), angular position (bearing), and velocity. Radar technology was developed for military use during World War II, but has now many civil applications, including air or marine traffic control, astronomy, ocean and meteorological monitoring, alti... » read more

Radar For Automotive: Why Do We Need Radar?

Communications and sensing technologies have transformed the automotive industry. More and more, cars include features and systems to interact with their environment, gaining awareness of the surrounding space, networking with each other and with the infrastructure, and detecting possible sources of danger. We can consider that vehicles have acquired their own “senses”: they know where they... » read more
