AUTOMOTIVE 4D IMAGING RADAR MARKET OVERVIEW

The global automotive 4D imaging radar market was valued at USD 0.19 billion in 2024 and is expected to grow to USD 0.37 billion in 2025, reaching USD 71.87 billion by 2033, with a projected CAGR of 93.4% from 2025 to 2033.

Radar is used in 4D imaging radar technology to provide three-dimensional images of objects as they move through space and time. This technology can be used for safety purposes, such as accident avoidance, to track the movement of people and vehicles. A potential new technique called 4D imaging radar produces high-resolution mapping for application in driverless cars. Currently, electric and semi-automatic vehicles with "Turn Assist" and "Adaptive Cruise Control" from Audi are popular because they can detect potential collisions using low-resolution radars. Higher automation, a broader field of view (FOV), a longer range, and all-weather visibility are among the new standards of 4D radar imaging that have been developed (rain, fog, dust, snowfall, and more).

Naturally, there are many 4D imaging radar sensors utilized to detect the large number of things on the road. The more interoperability there is between such sensors, the more automotive radar density used on the road. This is particularly true when we transition from basic comfort systems to extremely complex ones. As a result, the majority of component makers favor delivering radar-on-chip (ROC) or other types of integrated systems.

COVID-19 IMPACT

Disruption In Supply Chain Due To Lockdown To Hamper Market Growth

The global COVID-19 pandemic has been unprecedented and staggering, with automotive 4d imaging radar experiencing lower-than-anticipated demand across all regions compared to pre-pandemic levels.

Due to mandatory lockdowns and other restrictions set by the relevant regulating bodies in the wake of the recent COVID-19 outbreak, the activities of various industries have either been temporarily suspended or are running with small personnel. This element is expected to have a very unfavorable effect on the growth of revenue for the worldwide automotive 4d imaging radar industry, which is similar to other markets. Over the course of this projection period, the high expenses related to the installation and maintenance of these devices may potentially restrain the automotive 4d imaging radar revenue growth.

LATEST TRENDS

High Resolution to Enhance Performance of the Market

The use of the 4D imaging radar system to provide high-resolution photographs of several objects marks a significant departure from 2D radar. The beams produced by 4D imaging radar systems have a substantially broader field of vision (FOV), ranging from 90 to 120 degrees, in contrast to traditional radar, which only permits a narrow-concentrated beam (15 to 30 degrees). This enables to assess the environment in more depth contributes to automotive 4D imaging radar market growth.

• According to the U.S. National Highway Traffic Safety Administration (NHTSA), over 16% of new passenger vehicles sold in 2023 included Level 2+ driving features. Automotive 4D imaging radar is becoming a key enabler of these semi-autonomous systems by enhancing object tracking across 300+ meters with elevation accuracy under 10 centimeters.

• 4D imaging radar systems are increasingly integrated with onboard AI processors to improve lane-change decisions and pedestrian detection. In 2023, over 40% of newly developed 4D radar models supported 192 virtual channels or more, allowing higher spatial resolution and multi-target tracking at highway speeds.

AUTOMOTIVE 4D IMAGING RADAR MARKET SEGMENTATION

By Type

According to type, the market can be segmented into MIMO chip cascade and radar chipset.

In terms of product, radar chipset is the largest segment.

By Application

Based on application, the market can be divided into passenger vehicle and commercial vehicle.

In terms of application, passenger vehicle is the largest segment.

DRIVING FACTORS

Increased Usage by Government to Push Market Sales

Government organizations like the transport research laboratory (TRL) in England have significantly increased the use of 4D imaging radar in recent years to improve road safety and provide a better understanding of driver behavior through data analysis from video recordings taken by these vehicles' cameras. Additionally, a number of businesses have been concentrating on creating cutting-edge products that can offer solutions for traffic monitoring and management, which are rising to prominence among other applications globally.

Automotive Industries to Augment Market Growth

The market is divided into automotive, aerospace and defense, industrial, security and surveillance, and traffic monitoring & management segments based on application. Due to the rising demand for 4D imaging radars from various governments and automakers to build roads and highways, the automotive industry held the highest automotive 4D imaging radar market share. Additionally, over the projected period, it is anticipated that increased regulatory emphasis on raising safety standards in all key markets, including North America and Europe, will increase product demand.

• According to the European Commission, from July 2024, General Safety Regulations (GSR) will require all new cars sold in the EU to include forward-collision warning and lane-keeping technologies. Over 28 million vehicles annually in Europe are projected to be equipped with enhanced radar sensors to meet these safety criteria.

• Government subsidies on EV purchases in markets like China, Germany, and the U.S. have led to an increase in EV sales, with over 10 million units sold globally in 2023. These vehicles increasingly rely on 4D radar for sensor fusion alongside LiDAR and cameras, improving navigation accuracy in low-visibility conditions.

RESTRAINING FACTORS

On Target Specific Beam to Impede Market Expansion

For RADAR to lock on an object, more time is needed. Radio signals take longer to reach the target and return because they can freely travel across air and space. The beam range of RADAR is larger (Over 50ft Diameter). RADAR has a rather broad and non-target-specific beam range. Its range is shorter (200ft). RADAR signals have a limited range of 200 feet, in contrast to LiDAR. If an item is decelerating faster than 1mph/s, it cannot track it. It could be difficult for RADAR systems to gather data from an object that is moving.

• As per industry estimates, the cost of a 4D radar module can range from $150 to $300 per unit, which is significantly higher than traditional radar systems. This cost factor restricts adoption, especially in entry-level or budget automotive segments.

• According to a 2023 report from the International Automotive Technicians Network, less than 25% of service technicians globally are certified to calibrate advanced radar-based safety systems. This shortage affects post-installation accuracy and delays repair cycles for radar-equipped vehicles.
