The global radar sensors market size value reached around USD 19.05 Billion in 2024. The expanding automotive industry, particularly the increasing adoption of advanced driver assistance systems (ADAS) and autonomous vehicles, significantly boosts demand for radar sensors, which are essential for functions like collision avoidance and adaptive cruise control. In response, Mobileye and Valeo have collaborated to develop high-definition imaging radars for next-generation automated driving features. As a result, the industry is expected to grow at a CAGR of 17.20% during the forecast period of 2025-2034 to attain a value of USD 93.15 Billion by 2034. The rise in government regulations focused on vehicle safety standards further accelerates market growth.
Understanding Radar Sensors in Modern Applications
Radar sensors, or Radio Detection and Ranging sensors, are devices that use radio waves to detect the range, angle, and velocity of objects. These sensors play a pivotal role in multiple industries, from aerospace and defense to industrial automation. However, their most significant and fastest-growing application is within the automotive sector.
In vehicles, radar sensors are essential components in ADAS technologies, enabling features such as:
Collision avoidance systems
Adaptive cruise control
Blind-spot detection
Lane-change assistance
Automatic emergency braking
With growing consumer expectations for safer and more efficient driving experiences, radar sensors have transitioned from being luxury features to standard safety components in many mid-range and high-end vehicles.
