Chuhang Technology

The ARH1 77GHz 4D imaging millimeter-wave radar, developed and produced on Chuhang Technology's automotive-grade platform, features 6T×8R antenna channels, a point cloud of up to 6,000 points and a detection range of 300m, with high-speed feedback and alerting; its performance is comparable to LiDAR and it can be applied to L3 and higher autonomous driving scenarios. The product has upgraded its computing platform and RF front-end solution for more precise angular resolution, enabling fast and accurate discrimination of two targets at the same speed and distance; by adding vertical angular resolution in the pitch direction it stably obtains target height, effectively parses target contours or behavior, and achieves static target recognition and height detection, all in a highly market-competitive size. In October 2025 the company premiered its 4D satellite-architecture radar solution at SAECCE 2025, adopting a 'high-resolution 4D radar based on waveguide antennas + 5R satellite architecture' and a 'front-end sensing + central computing' architecture. Based on a single-chip 8T8R MMIC satellite radar chip and proprietary waveguide antenna technology, it supports wideband coverage of 76-81GHz and can achieve collaborative anti-interference among the vehicle's 5 radars via OTA upgrades, adapting to the future 79-81GHz band without hardware replacement; detection range is extended to 450m, angular resolution reaches 1°, and point cloud density increases by 680%. With dimensions of 60.7mm×83.2mm×23.6mm (excluding mounting lugs), it is one of the smallest forward radars in the industry. It adopts a POC coaxial connector rear-exit solution and supports multi-radar point cloud fusion processing, and has already won a mass-production project designation from a leading Chinese NEV manufacturer. In addition, the company's 4D forward radar and 4D corner radar have entered scale mass production; the 4D corner radar has won designations and mass production for six major functional applications and has entered the two-wheeler sector (Yadea, etc.).

A consumer-grade 24GHz corner radar platform product (IRM1). The Pilot project enables power-line inspection drones to use it as an obstacle avoidance radar, avoiding obstacles such as tree branches, utility poles, guyed wires, wire mesh and pedestrians during flight to ensure safe flight of power-line inspection drones. When used on crop protection (agricultural) drones, it provides tip-height determination, forward and rear terrain height prediction, and output of obstacle target information to the flight controller during flight (terrain following + obstacle avoidance).

Millimeter-wave radar has good penetration capability and is not limited by climate, environment or lighting, allowing accurate determination of the state and flow of vehicles and pedestrians on the road. Mounted on urban street lights it can upgrade them into smart street lights, providing traffic flow monitoring, delivering signal-change data and energy-saving services for smart transportation, and effectively monitoring drivers' bad driving behavior. Application areas include smart parking lots (monitoring vehicle flow in and out) and smart street lights (monitoring traffic and pedestrian flow at intersections or on roads).

Uses FMCW frequency-modulated continuous-wave millimeter-wave radar to accurately detect the speed and distance of multiple targets; all-around installation enables environmental perception within a 200m range (shorelines, vessels, reefs, etc.), avoiding collisions, grounding and other shipping risks. High carrier frequency provides strong spatial resolution and imaging capability; high system sensitivity and low false alarm rate enable functions such as automatic berthing. It can penetrate haze and rain or snow, with horizontal and vertical detection complementing each other; it can also effectively perform load measurement and warning, and compensates for height fluctuation in both anti-collision and automatic berthing applications.

Based on millimeter-wave radar technology, it detects and recognizes moving indoor targets and can count the number of people indoors. It can be combined with indoor lighting systems to automatically control light switches: when the radar detects a moving target indoors, the lights turn on automatically; when no moving target is detected within 30 minutes, the lights turn off automatically. Application areas include office buildings, large factories and warehouses.

Leveraging the immunity of millimeter-wave radar to environmental and lighting conditions, it can be installed in private places such as hotels and homes to detect the heartbeat and respiration of monitored subjects while protecting privacy, checking for the presence of live bodies and abnormal heartbeat or respiration in enclosed spaces. In events such as sudden heart attack or an elderly person falling, the radar can connect to a smart home warning system for end-to-end alerting to save lives in time. Application areas include hotels, schools, home bedrooms and bathrooms; the company has also formed a strategic partnership with Linghang Yizhi to jointly develop vital sign monitoring millimeter-wave radar products for the smart elderly care sector.
