Market demand and challenges of USRR Auto driving and advanced driving assistance systems generally consist of sensing, controlling and actuation. Sensing relies on sensors of all sorts such as mmWave radar, cameras, laser radar and ultra sound wave. Front long-range radar and corner radar are applications of mmWave radar that we are familiar with. They are employed in highway and urban road driving scenarios to realize functions like ACC, AEB, BSD and LCA. The Alps family of SoC chips that Calterah brought about in 2019 well facilitates the development and realization of these two kinds of radar. The following scenarios are no strangers to us: In peak hours, roads are combusted with vehicles. Positioning will be much harder when there is an obstacle above the vehicle, an overpass for instance. In a big parking lot, there is trouble finding space and parking a car. The absence of separation of pedestrians and vehicle leads to a greater chance of traffic accidents. (Pictures from online sources) What these scenarios have in common is complex road conditions, slow driving speed, and necessity for drivers to have a good sense of surrounding situations. However, existing sensors are barely satisfactory in short-range coverage. Ultra sound……
Recently, TÜV Rheinland issued ISO 26262 Functional Safety Management Certificate to Calterah Semiconductor, making Calterah one of the two fabless design houses in China semiconductor industry that has achieved this certification. Covering the functional safety requirement planning, design, implementation, integration, verification, confirmation measures and configuration, ISO 26262 series of automotive functional safety standards is one of the market thresholds for E/E part suppliers to enter the automotive industry, with the aim of minimizing the risks from automotive E/E system failures through comprehensive development processes. ISO 26262 series of standards provides a risk-based approach to determine automotive safety integrity levels (ASILs). There are four ASILs defined, ASIL A, B, C and D, with D representing the highest level and A the lowest level. A higher ASIL level means more stringent requirements on system safety, hardware diagnostic coverage and development processes, which also puts a higher demand on technology. ▲Calterah Obtained ISO 26262 Functional Safety Management Certificate Based on ISO 26262:2018, Calterah Semiconductor has established a complete set of functional safety product development process, which supports the development of IC products with up to ASIL D level.

Together, we will win the battle against the 2019-nCoV. Since the outbreak of the epidemic, Calterah has always been with the frontline medical staff, and has taken proactive action in purchasing anti-epidemic materials through multiple channels. Recently, the goggles donated by Calterah have been successfully delivered to the designated hospitals in Wuhan. Dr. Chen Jiashu, the CEO of Calterah, said that we should be neither overconfident nor oversensitive to the epidemic. With our joint efforts, we can definitely defeat the virus. Currently, the epidemic still continues. Since the resumption of work, Calterah has taken various measures to ensure the safety of employees. Employees must have their body temperature measured at the front desk and ensure that their temperature is normal before entering the offices each morning; lunches are all ordered by the company to reduce outdoor activities; masks, disinfectants and sterilizing lamps have been purchased; the offices are disinfected every night; online meetings are recommended whenever possible to avoid gatherings. We do everything we can to fight against the epidemic. Aiming to tide the frontline staff over the difficulty, Calterah, in the meantime, will continue purchasing anti-epidemic materials via various channels and send them to the frontline as promptly as……
With the increasing number of automobiles, a higher demand is put on the vehicles access management system applied at entries and exits. At present, sensors used for managing the access of vehicles and human body are mainly camera sensors, active infrared intrusion detectors, and ground induction coils. Among others, camera sensors are the most widely used, demonstrating stable performance in well-lit environments. However, the performance can be influenced by complicated environments such as night, fog, and haze, making all-weather operation unachievable for camera sensors. That’s why cameras mainly function as triggers in the barrier gate application. An active infrared intrusion detector consists of a pair of transceiver devices configured onto the both sides of the barrier gate, requiring precisely aligned configuration and relatively complicated layout and routing. The major problem lies in that it is easy to be hidden by objects (small animals, branches, etc.,), causing false triggers. Another common sensor is ground induction coil sensor. Substantially, ground induction coils are multiturn coils. They can form a magnetic field and thus sense the access of vehicles according to the principles of electromagnetic induction. When configuring such a kind of sensor, it is inevitable to damage the road surface and bury……

The application of millimeter wave (mmWave) radar technology for indoor detection and tracking of the human body has just been emerging in recent years. The underlying principle is that electromagnetic wave signals emitted through radar antenna shall be reflected after being blocked by objects on its emitting path and be received by the radar receiving antenna, so that through a series of processing of the received signals, the distance, velocity, and angle information of the object can be obtained. At present, besides mmWave radar, ultrasonic sensors, passive infrared sensors, active infrared sensors (such as LiDAR and ToF), and optical cameras are also used for indoor detection and tracking of the human body. However, these sensors can be easily affected by external environment conditions (for example, light, temperature, etc.), causing false alarms. By contrast, mmWave radar can operate stably and reliably 24/7 under all-weather conditions, demonstrating superior performance in meeting the requirements of indoor detection and tracking of the human body. That’s why mmWave radar is more and more widely used in security monitoring, smart home, smart elderly care, automatic door control, and other fields. When it comes to personal privacy, in particular, mmWave radar has irreplaceable advantages against others. Calterah……
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……
