IAA 2023 | Calterah to Exhibit Andes mmWave SoC, Boasted Unmatched for 4D Imaging Radar

Leading Chinese provider of mmWave radar SoCs, Calterah Semiconductor, will be showcasing its most comprehensive product portfolio of automotive mmWave radar SoCs, including the most sought-after next-gen Andes SoC for 4D imaging radar, at the world’s largest and most important mobility event, IAA Mobility 2023 from September 5 to 10, at Booth A2-F31 of Messe München in Munich, Germany.

The cutting-edge technology of 4D imaging radar, creating a buzz in the mmWave sensing field, delivers high-resolution and long-range object detection across four dimensions: distance, velocity, azimuth, and notably, elevation. This crucial elevation detection capability distinguishes it from traditional 3D mmWave radar systems. By capturing object information in all four dimensions, it generates denser point cloud data, enhancing imaging quality and giving rise to the term “imaging radar”. Compared to standard mmWave radar, 4D imaging radar offers several advantages, including a wider field of view (FOV), enhanced accuracy, exceptional resolution, improved height measurement, and the ability to identify stationary objects and smaller targets beyond vehicles.

The next-gen Andes SoC (CAL77C844-AF) from Calterah is fully prepared to meet the demands of  4D premium and imaging radar applications. Like other Calterah SoCs, the Andes integrates radar transceiver and microprocessor functions seamlessly. In the competitive radar sensor market, the Andes stands out for its unmatched capabilities.

  • Multi-Core CPU with DSP and RSP

The Andes SoC integrates four CPU cores to deliver substantial computational power, a DSP offering at least 2X to 9X faster digital signal processing, and a proprietary RSP for swift radar signal processing. These all translate into a significant edge in signal and data processing and executing advanced algorithms, outshining the competition.

  • Flexible Architecture

The flexible architecture equips the Andes SoC for diverse usage scenarios and waveform requirements. With a 7-bit phase rotator enhancing resolution and accuracy, its RF subsystem also supports flexible waveform generation, precise digital compensation, and an optimized floorplan for improved isolation. Another testament to its flexibility is the innovative Flex-Cascading function with C2C interfaces, facilitating the creation of powerful 4D imaging radar systems of various scales by cascading different numbers of CAL77C844-AF SoCs.

  • Convenient Debugging Functions

The intricate development process of imaging radar demands convenient debugging functions. To address this need, the Andes SoC offers an array of user-friendly debugging features through various debugging interfaces, channels, and analytic modules.

  • Advanced Security Capability

In response to the growing demand for automotive cybersecurity, Andes integrates a Hardware Security Module (HSM) meeting the requirements of a vehicle’s main control chip. With a “safety island” design, it ensures exclusive access to resources for the CPU within the HSM. Additionally, crypto hardware accelerators within the HSM reinforce common encryption and decryption algorithms, enhancing the cybersecurity of vehicle systems.

Based on a configuration of two cascaded Andes SoCs, Calterah has developed a 4D imaging radar solution offering exceptional detection capabilities: azimuth resolution of 1.5°, azimuth accuracy of ±0.1°, elevation resolution of 4°, a maximum target count of 2048, and more. Notably, unlike radar systems reliant on cascaded MMICs, Calterah’s 4D imaging radar solution obviates the need for an additional MCU due to the high integration level of Andes SoCs, resulting in a more cost-effective radar system. With outstanding detection capabilities and cost-efficiency, the Calterah 4D radar solution powered by Andes SoCs is poised to empower more L3+ ADAS systems, advancing the landscape of autonomous driving.
