In recent years, fueled by the popularity of smart cars and advances in radar chip manufacturing, the domestic millimeter-wave radar market has grown rapidly.
Data from the first quarter of 2025 shows that China's installed base of in-vehicle millimeter-wave radars reached 6.263 million units, with models in the 100,000-300,000 yuan price range driving the growth. The penetration rate of forward-facing radars jumped from 39.1% to 46.7%. In the consumer electronics sector, low-power millimeter-wave radars are enabling contactless interactions in scenarios such as smart homes and security monitoring.
Millimeter-wave radars are beginning to enter the homes of ordinary people: human presence detection in smart door locks, blind spot monitoring for electric bicycles, and gesture control for smart homes—these innovative applications are reshaping the consumer market.
To better share cutting-edge developments in the millimeter-wave radar ecosystem with industry colleagues, and to more deeply analyze its value and promote its development, the "IOTE 2025 Shenzhen Millimeter-Wave Radar Technology Ecosystem Seminar" was successfully held at Hall 10, Venue 3, Shenzhen International Convention and Exhibition Center (Bao'an New Hall) on the afternoon of August 27. The seminar was hosted by the Shenzhen Internet of Things Industry Association and co-organized by IoT Media, IOTE, AIoT Star Map Research Institute, and AIoT Library.
This conference, a sub-forum of the "IOTE 2025, the 24th International Internet of Things Exhibition," focused on the application scenarios, technical challenges, and cutting-edge trends of millimeter-wave radar, inviting representatives from various industry sectors to attend.
Participating company representatives included: Guo Xuefeng, Head of Radar Product Line at the Hong Kong Applied Science and Technology Research Institute; Huang Zhiyuan, CEO of Migan Technology; Xu Hongtao, CEO of SiDian Micro; Lu Yumin, CEO of Sijie Micro; Pan Pan, COO of Zhenghe Microchip; and Liu Houliang, COO of Miaomi Technology.
These guests delivered fascinating presentations at the conference, and Core Sensor has compiled the highlights of their presentations for you after the event.
Speaker: Guo Xuefeng, Head of Radar Product Line, Hong Kong Applied Science and Technology Research Institute
This presentation analyzed millimeter-wave radar: its 12 core indicators (range, speed, horizontal/vertical angle range/accuracy/resolution), including parameters related to the radar equation; outlined the signal processing process (preprocessing → 1D/2D/3D FFT → CFAR detection → angle estimation → clustering → tracking); and presented a comprehensive technology overview, including the industry chain (upstream: chip vendors such as NXP, TI, and Calterah Microelectronics; midstream: product vendors such as BOSCH and Huawei; downstream: automotive, industrial, and other scenarios), hardware and software, technology classifications, and development trends (such as 4D imaging radar and multi-sensor fusion). The presentation further elaborated on UWB interawareness: its advantages (centimeter-level accuracy, multipath interference resistance, low latency, etc., compliant with IEEE802.15.4z) and spectrum (3.1-10.6GHz); compared the core differences between UWB radar, millimeter-wave radar, and cameras (UWB has strong penetration, privacy, and environmental adaptability, while cameras have weaker ones); listed application scenarios (CPD, SM, KTO, and DK), and explained the positioning principle (based on concentric antenna arrays, estimating TOA and AOA using CIR, and calculating phase difference and distance to achieve single-anchor positioning).
Finally, the presentation discussed AI edge computing: clarifying the relationship between AI, ML, and DL; explaining the core of edge computing (distributed data and computing) and its advantages; and outlining the training and inference process (8:1:1 data distribution, from preprocessing and training to deployment and inference), as well as the key steps and post-training outputs of machine learning. Using motorcycle millimeter-wave radar software as an example, the application process (signal processing to generate a point cloud → preprocessing → clustering → tracking → BSD decision-making) was demonstrated.
Speaker: Huang Zhiyuan, CEO of Migan Technology
This presentation focused on the "Current Status and Outlook of Consumer Radar," systematically expounding on the current state of the consumer radar industry.
Mr. Huang pointed out that consumer radar is currently experiencing differentiated development trends, with low-frequency and high-frequency radars. Low-frequency microwave radar (such as 5.8GHz/10GHz) is highly popular, boasting advantages such as a comprehensive product portfolio, high cost-effectiveness, and wide application. It has been widely used in smart lighting, smart home, and bathroom applications. The domestic market is expected to see continued growth and price declines between 2023 and 2026, lowering the barrier to entry thanks to a mature industry chain. However, its technical bottlenecks are significant: its reliance on the Doppler effect results in weak static detection capabilities, making it difficult to distinguish targets at the same distance and speed, its poor anti-interference capabilities, its inability to obtain angular information, and its limited functionality expansion.
While high-frequency millimeter-wave radar holds great potential, it faces numerous challenges in implementation. Currently, issues such as insufficient radar algorithm capabilities, high development resource investment, long project development cycles, high costs, and insufficient scenario adaptation and polish hinder its large-scale application.
Speaker: Xu Hongtao, CEO of Silicon Micro
This presentation focused on the core pain points and solutions in millimeter-wave technology applications, highlighting how the ultra-compact ICL111A AiP (antenna-in-package) SoC and its supporting ecosystem overcome the challenges of traditional millimeter-wave development and deployment.
Mr. Xu pointed out that traditional millimeter-wave solutions face multiple challenges, including bulky size, high cost, complex production, environmental sensitivity, and long development cycles. The ICL111A achieves high integration in an extremely small form factor (minimum 5.5×5.5mm, maximum 12×12mm), saving approximately 90% of system space and significantly reducing hardware size and thickness. It is suitable for a variety of compact terminal devices, including smart lighting, switches, home appliances, and smart screens.
This chip not only achieves "miniaturization, low power consumption, and high cost-effectiveness" at the hardware level, but also provides "easy-to-develop, open-enabling" software and hardware support through the Xen series reference designs and ONE Lab development kit. This includes documentation, algorithms, development tools, and technical support, significantly reducing development barriers and cycles (from "months" to "days"), helping customers quickly achieve productization.
Speaker: Lu Yumin, CEO of Sijiewei
This presentation focused on millimeter-wave radar products and market progress, covering radar technology principles, technological innovations, multi-field application scenarios, and the company's core capabilities.
Mr. Lu stated that the core reason millimeter-wave radar has become a key technology for intelligent perception lies in its ability to accurately capture target information in three dimensions: distance, angle, and speed. Distance detection relies on the time-of-flight of electromagnetic waves, with signal bandwidth determining resolution; angle recognition relies on antenna angle differences, with the number of antennas directly affecting resolution accuracy; and speed measurement is achieved through Doppler shift; the longer the measurement time, the higher the speed resolution.
In terms of technology, the currently mainstream pulse radar, frequency-tunable continuous wave radar (FMCW), and phase-tunable continuous wave radar (PMCW) each have their own advantages. FMCW radar, due to its stable signal transmission and reception characteristics, is widely used in various scenarios. A complete millimeter-wave radar sensor consists of an antenna for beam transmission and reception, a transceiver for processing RF signals, and a signal processing module for data calculation. The coordinated operation of core components such as the LO, LNA, and VGA ensures accurate and efficient detection.
