The global market for 4D imaging radar technology is growing quickly, with experts predicting a big increase from USD 392.8 million in 2025 to USD 1,206.9 million by 2030. The market was valued at USD 335.7 million in 2024, and with a compound annual growth rate of 25.2%, it is one of the fastest-growing areas in advanced sensing technology. This growth is mainly because of the rising need for real-time, high-resolution systems that help with automotive safety, autonomous driving, and various industrial and defense uses.

A major reason for this growth is the increasing use of autonomous and semi-autonomous vehicles. As car manufacturers and tech companies work toward full self-driving capabilities, 4D imaging radar is becoming important for safer driving and improved awareness of the surroundings. Governments are also helping by setting stricter safety rules for vehicles, which is pushing automakers to include more advanced driver assistance systems in their cars.
Beyond the automotive industry, this technology is also being used in aerospace, healthcare, and manufacturing, where accuracy and real-time information are vital. 4D radar systems provide detailed images combined with motion data, allowing precise tracking of moving objects even in bad weather or poor visibility.

Companies like VisionWave Holdings Inc., Arbe Robotics Ltd. , RTX Corporation RTX), Kratos Defense & Security Solutions, Inc., and Leonardo DRS, Inc. are working on military-grade radar systems. These companies are creating systems that can detect, identify, and track threats in real-time, including hard-to-detect objects like low radar cross-section projectiles and drones.
For example, VisionWave recently finished a five-day live-fire test in the UAE. Their 4D super-resolution radar, paired with their Evolved Intelligence (EI) edge engine, showed high-speed accuracy and fewer false alarms when detecting complicated threats. Noam Kenig, CEO of VisionWave, said their radar is built to make quick decisions and work smoothly with countermeasure systems. He added that the radar offers high accuracy and wide coverage, setting a new standard for active protection systems in defense. In the Asia Pacific region, countries like China, India, Japan, and South Korea are playing a big role in the market’s growth. This is due to increasing consumer interest in advanced safety features and strong government rules requiring the use of radar and sensor systems. As car makers adapt to these trends, the region is likely to have the highest growth rate in the global market. The growing need for better awareness, affordable system integration, and flexible designs is pushing manufacturers to develop new and better systems quickly. With use expanding in both commercial and defense areas, 4D imaging radar is moving from being a rare innovation to a key technology supporting future advancements in safety, automation, and threat detection.
