Every year, EE Times publishes an annual edition of its Silicon 100, a list of startups that merit everyone’s attention. Following the debut in last year’ s list, Calterah was named again in the recently released 2021 list, standing out as the only Chinese mmWave radar chip company. 2021 List of Silicon 100 Released Silicon 100 looks at various aspects, including tech strength, target market, financial status, financing, corporate maturity and leadership. And it is believed to be insightful for the investment world. As usual, startups in this year’s list fall into the categories of AI, machine learning, neural network, auto electronics and semiconductor manufacturing that hold promise for the future. Calterah as a leading provider of CMOS mmWave radar chips keeps going beyond what has been achieved with stress on IP and innovation and building greater capacity in providing solutions to ultimately reduce time for customers to develop radar systems with our products. Being named in Silicon 100 again speaks volume about the attention and recognition Calterah receives. And Calterah will continuously provide easier-to-use and more power-efficient mmWave radar chips and make mmWave serve everyone.

On June 25, the 1st three-day Calterah Auto-Technical Open Days came to a successful end. The event was carried out in the form of a workshop and brought together many Calterah’s partners and customers, some of whom are the leading Tier-1s in the automotive industry. Centering on mmWave radar technology, the workshop delivered in-depth lectures and discussions about practical issues regarding algorithms for auto applications, code compiling, debugging and the use of certain software.   Calterah Application Engineers Giving Lectures A Lecturer Having an In-Depth Exchange with an Attendee Customers expect greater support from Calterah in implementation of radar algorithms as they go deeper into the development with our mmWave radar chips. To better help customers understand the logic and performance of our chips, we held this three-day workshop comprising different sessions, presided by our application engineers as lecturers, to address 10 issues around SDK architecture, compiling environment setup, interfaces for drivers and algorithm debugging. Throughout the workshop, Calterah field application engineers were also present, ready to instruct hands-on exercises and answer questions in a more interactive manner. FAEs Instructing Hands-On Exercises When asked about how they felt at the end of this event, one attendee applauded the workshop as……

On April 14, Automobil Industrie of Vogel China held the 2021 International Forum on Revolution and Innovation of Automotive Electronics and an awarding ceremony was given to recognize outstanding persons and enterprises in innovation, among which Calterah was honored with the Fastest-Growing Enterprise Award. Group Photo of Awarded Enterprises (Calterah, Second from the Left) To award persons and enterprises with active contribution to the revolution and innovation in the automotive electronics industry, and promote the progress of the industry, Automobil Industrie set up three awards, Leading Enterprise, Fastest-Growing Enterprise and Elite Figure, and initiated the selection process in Feb. 2021 through ways like online voting. Calterah as an emerging player in the mmWave radar chip field brought itself under the spotlight and won the Fastest-Growing Enterprise Award. Calterah, a global leader in designing and developing CMOS single-chip mmWave radar sensors, mass-produced the world’s first CMOS 77/79-GHz mmWave RF front-end radar-on-chip for automotive use, and in 2019 rolled out SoC products with radar signal processing baseband, which brought revolutionary changes to the development of mmWave radar sensors. Later on it productized the Antenna-in- Package (AiP) technology and also achieved the mass production of the AiP products, accelerating the general applications of……

Breakthroughs Powered by AiP In 2019 Calterah released an indoor human detection solution powered by 60-GHz/77-GHz mmWave radar chips for positioning and tracking personnel inside a room. Together with the vital signs detection solution, it enables us to know whether there are people inside a room and how their vital signs are. On top of that, Calterah this time works out an AiP-based mmWave radar solution with new features like 3D object tracking and facility measurement, which offers a new direction and choices for markets of smart home, consumer electronics and senior care.   3D Object Tracking With high range resolution of Calterah AiP mmWave radar sensor chips, both azimuth and elevation can be measured at the same time and therefore rich point cloud data of the measured object can be obtained. By processing such data, the distribution of the points in 3 dimensions (length, width and height) can be understood. Based on the relations among the distribution in 3 dimensions and changes in height in a time period, the posture (standing, sitting, lying and falling down) of the measured object can be determined, thus addressing the need to distinguish among adults, children and pets. When combining the 3D object……

With the rapid development of Advanced Driver Assistance Systems, or ADAS, an increasing share of new vehicles has been mounted with mmWave radar sensors these years. The problem follows and becomes even more apparent that radar signals among different vehicles will interfere with each other. In response to this, Calterah comes up with a solution powered by its Alps radar SoC. Before going further, let’s first have a look at the commonly seen signal interference between radar sensors. Fig. 1 shows how FMCW radar signals are typically interfered. Suppose a working radar sensor receives chirp signals from a nearby radar sensor and the interference signal frequency approximates to the frequency of the working radar sensor. Then the interference signals will go into the IF bandwidth of the working radar sensor, as shown in Fig, 2. As seen, the interference signals affect the waveform of working radar signals a lot and therefore it is very likely that desired target signals are missed or false target occur.  Fig. 1 Fig. 2 To address this issue, baseband of Alps SoC provides several anti-interference features, including the Frequency Hopping mode, Chirp Shifting mode, Phase Scrambling mode, and the interference mitigation function. 1.Frequency Hopping In……
