Millimeter wave radar is known as an important sensor for Advanced Driver Assistance Systems (ADAS) and autonomous driving in automotive industry. Compared with other sensors, radar can operate stably and reliably in challenging environments like rain, snow, fog and dust. Distance and velocity are direct measurements of a radar sensor, so it’s easy to estimate the motion status of a detected target for a radar sensor. In ADAS, radar is often working together with camera sensors or other sensors. For this kind of systems, sensor fusion is an efficient way to use all information compared with using information independently. Data synchronization is important to any kind of sensor fusion. Generally, a camera sensor provides results at about 30 frames per second (FPS). In ideal case, the results can be fused by frame, which means the radar sensor should also be able to output data at 30 FPS. Automotive radar technology is growing fast in recent years. A cutting-edge ADAS radar sensor can process thousands of reflected targets and track hundreds of them in a single frame. Even the angular resolution, which is traditionally thought of as a short slab of radar, has been improved greatly by newly developed cascade and……
Calterah is building up the IC development process following the ISO 26262 standard, and cooperating with “TüV Rheinland” for ASIL B certification for Alps and for development process certification.
Calterah Semiconductor, as a leading mmWave radar sensor chip provider, was invited to the International Wireless Industry Consortium (IWPC) Year 2019, held in Germany. At the workshop, Dr. Zhu Yan with Calterah Semiconductor, delivered a speech entitled “Cascade Radar System–A System-on-Chip Approach”.
