Industry Overview
A mmWave radar is an active detection sensor operating in the 30-300GHz frequency band with a wavelength of 1-10mm, positioned between microwave and infrared. By transmitting millimeter waves and receiving target echoes, it accurately calculates distance, speed, angle, and azimuth information. It features a compact size, high resolution, and strong resistance to interference from rain, fog, smoke, and dust, enabling stable all-weather operation. Compared to optical sensors, it is less affected by environmental conditions, and compared to microwave radars, it offers higher precision.
Industry Development Background
The government has established a full-lifecycle policy system for mmWave radar, spanning strategic planning, spectrum allocation, standard formulation, and mandatory installation. "Made in China 2025" and the "Innovation and Development Strategy for Intelligent Vehicles" clarify the industry's positioning. The Ministry of Industry and Information Technology (MIIT) has opened the 76-81GHz dedicated frequency band and simplified management procedures. National standards have tightened AEBS and radar precision requirements, driving the maturity and domestic substitution of 77GHz/4D imaging technologies.

Industry Chain Structure
In the upstream of the mmWave radar industry chain, MMIC chips and high-frequency materials remain dominated by international players, while domestic breakthroughs are accelerating. In the midstream, module and 4D radar technologies are iterating rapidly, becoming a core growth pole. In the downstream, automotive ADAS and autonomous driving drive demand, with smart transportation and industrial scenarios expanding the application space. Driven by the dual engines of policy and technology, 77GHz/4D imaging has become mainstream. The industry chain is evolving towards independent and controllable, highly integrated, and low-cost solutions, supporting the scaled deployment of intelligent driving.
Market Development Status
In 2024, the global mmWave radar industry market size reached 29.1 billion RMB, with a compound growth rate of 13.1% from 2020 to 2024. The penetration of automotive ADAS and autonomous driving serves as the core driver. With 77GHz becoming mainstream and 4D imaging radars rapidly scaling up, coupled with mandatory AEBS installation and declining costs, the industry is experiencing growth in both volume and value. The industry has entered a stage of rapid growth characterized by parallel technology iteration and scaled popularization.
In 2024, the market size of China's mmWave radar industry reached 9.8 billion RMB, with a compound growth rate of approximately 16% from 2020 to 2024. The standardization of automotive ADAS, mandatory implementation of AEBS, and the iteration of 77GHz/4D imaging technologies are the core drivers. The market share of domestic manufacturers continues to rise, and scenarios such as smart transportation and industrial perception are expanding the demand boundaries. The industry shows a trend of simultaneous growth in volume and value, with the local supply chain accelerating breakthroughs, making it the fastest-growing core market for mmWave radar globally.
Competitive Landscape
Looking at the global mmWave radar industry landscape, companies such as Bosch, Continental, and Aptiv hold the majority of the global market share relying on their patents and mass production experience. In China, the domestic substitution rate for corner radars exceeds 55%, and the share of forward-facing radars has risen to 13.3%. 4D imaging has become the focus of competition. Companies like Huawei and Desay SV are rapidly iterating 77GHz/4D technologies with significant cost advantages. The industry is evolving towards high integration, domestic substitution, and 4D capabilities. Driven by the dual engines of domestic substitution and technological upgrading, the market landscape is continuously being restructured.
Industry Development Trends
The mmWave radar market takes automotive ADAS as its core, with smart transportation and industrial perception as incremental drivers, continuously broadening application scenarios. The automotive sector accounts for over 80% of total demand. The increased penetration rate of L2+ and the mandatory standardization of AEBS have driven the number of radars per vehicle to 5-8 units. 4D radars are becoming standard for L2+/L3, and 2026 is expected to usher in the first year of scaled in-vehicle deployment. In the smart transportation sector, the construction of roadside radars and vehicle-road coordination is accelerating, with the opening of the 92-94GHz dedicated frequency band supporting high-precision traffic monitoring. Scenarios such as industrial, security, smart home, and medical life detection are rapidly scaling up, and 60GHz radars are becoming popularized in indoor perception and vital sign detection. The global market maintains double-digit growth, with the Chinese market leading the growth rate, reaching a scale of 9.8 billion RMB in 2024, a year-on-year increase of over 16%. Driven by the triple forces of policy, technology, and market, the industry is extending from a single automotive focus to multiple scenarios. Scaled applications further dilute costs, forming a virtuous development pattern of "automotive as the main growth driver and scenarios expanding boundaries."
