Radar Sensors - Market Share Analysis, Industry Trends & Statistics, Growth Forecasts (2025 - 2030)

The radar sensor market size is at USD 24.54 billion in 2025 and is projected to reach USD 53.12 billion by 2030, expanding at a 16.7% CAGR.

The rapid scaling reflects the technology's migration from exclusive defense use to high-volume automotive safety, industrial automation, drone mapping, and smart infrastructure programs. Adoption is propelled by safety regulations such as the European Union General Safety Regulation, which mandates automatic emergency braking using 77-81 GHz radar in new vehicles. Supply-side catalysts include affordable millimeter-wave chipsets and gallium-nitride power devices that enhance range resolution while lowering size, weight, and power requirements. Robust military modernization in Asia-Pacific, expanding 5G-enabled road projects in Europe, and climate-resilient weather radar networks worldwide deepen addressable demand. Near-term challenges center on below-10 GHz spectrum congestion, calibration expenses for imaging arrays, and gallium supply risks stemming from China's 98% production dominance.

Global Radar Sensors Market Trends and Insights

Increasing adoption of 77-81 GHz radars in automotive safety systems

Regulators and automakers endorse 77-81 GHz because it delivers longer detection ranges and sharper angular resolution than legacy 24 GHz devices. Continental's ARS640 exceeds 300 m range and enables object classification fit for Level 2+ autonomy. China's Ministry of Industry and Information Technology halted new 24 GHz radar approvals in 2022, compelling local OEMs to shift frequency bands. Bosch extended the band to motorcycles, equipping KTM bikes with 210 m range radar for adaptive cruise and blind-spot warning. These developments reinforce steady sensor penetration across vehicle classes, underpinning radar sensor market growth.

Surging demand for compact imaging radars in drone-based terrain mapping

Multirotor drones use lightweight synthetic-aperture radars to generate sub-meter elevation models even in vegetation or cloud cover where optical payloads fail. Research shows 72.73% of mining exploration missions now favor multirotor over helicopter platforms, cutting survey cost by 60% while improving spatial granularity. The U.S. Geological Survey's mobile radar observatory captures rainfall-runoff data minutes after wildfires, supporting emergency response. Such proof points fuel R&D investment in higher-bandwidth chipsets and on-board processing, broadening the radar sensor market.

Spectrum allocation constraints in sub-10 GHz bands

Radar developers compete with telecom and satellite operators for scarce sub-10 GHz slots. The U.S. Department of Defense runs more than 120 radars below 3 GHz, limiting civilian spectrum re-farm potential. The FCC recently tightened 24 GHz out-of-band limits to satisfy global rulings, forcing design changes. Certification queues can stretch nine months, delaying product launches and curbing near-term radar sensor market adoption.

Other drivers and restraints analyzed in the detailed report include:

1. Rising military spend on AESA radars in Asia-Pacific
2. Growing need for mm-wave sensors in industrial robot collision avoidance
3. High calibration & maintenance cost of imaging radar arrays

Segment Analysis

Non-imaging devices represented 71% of 2024 revenue, illustrating entrenched use in parking assistance and basic adaptive cruise. Imaging solutions, however, are forecast to post an 18.4% CAGR through 2030 as Level 2+ autonomy proliferates. NXP and sinPro's 48-channel entry-level 4D unit reaches 1-degree azimuth and 2,000 point clouds per frame, signaling democratization of high-resolution perception. Imaging capability lets automated brakes distinguish pedestrians from roadside signs, pushing OEM fitment beyond luxury trims. The radar sensor market size for imaging-enabled modules is projected to reach USD 11.3 billion by 2030, capturing escalating software-defined vehicle budgets. Conversely, the cost-optimized non-imaging category retains dominance in delivery robots, forklift collision alerts, and rainfall estimation where identification finesse is less critical. Manufacturers bundle simple FMCW dies with antenna-in-package designs to lower bill-of-material cost and sustain the wider radar sensor market.

Competitive roadmaps now combine embedded signal processors with edge AI acceleration to shrink latency. Continental's ARS640 integrates neural network filtering to classify vulnerable road users in real time, raising functional safety metrics. On the materials side, silicon germanium front-ends challenge GaAs incumbents, promising sub-USD 10 die price at high volumes. This cost curve supports incremental imaging upgrades in mid-segment cars and paves the way for radar sensor market penetration in scooters and micro-mobility.

The 77-81 GHz tier held 43% 2024 revenue due to a sweet spot between path loss and antenna aperture, enabling 250 m automotive detection while remaining cost-effective. Regulatory harmonization in Europe, China, and North America cut certification complexity and boosted the radar sensor market. STMicroelectronics' 77 GHz transceiver sustains performance in snow or dirt, validating use in harsh roadside units. Above 94 GHz, ultra-wideband channels achieve sub-centimeter resolution prized in pavement crack monitoring and medical micro-Doppler imaging. With a 21.7% CAGR, >=94 GHz shipments are set to more than triple by 2030 as wafer-scale GaN power amplifiers mature.

Spectrum below 10 GHz faces saturation, pushing developers to migrate upward. China no longer approves new 24 GHz automotive radars, accelerating global pivot. Short-range 60 GHz gear excels in cabin sensing, occupancy detection, and gesture control; Texas Instruments' single-chip radar improves child presence alert accuracy to 98% without cameras. Blended multi-band architectures deploy 24 GHz corners, 77 GHz front units, and 60 GHz interiors, expanding the radar sensor market across multiple tiers.

The Radar Sensor Market is Segmented by Type (Imaging Radar, Non-Imaging Radar), Frequency Band (More Than 10 GHz, 24 GHz ISM Band, and More), Range (Short-Range Radar Sensor, Medium-Range Radar Sensor, and More), Technology (Pulsed Radar, Phased-Array / AESA Radar, and More), End-User and Geography.

Geography Analysis

North America remained the largest regional contributor in 2024, supported by advanced driver-assistance deployment and sizable defense upgrades. Gallium supply risk, however, threatens USD 602 billion of U.S. economic output, pushing policymakers to localize GaN epitaxy and recycle scrap csis.org. The United States also grapples with certification delays that slow civilian rollouts, while Canada scales automotive radar test facilities and Mexico benefits from near-shoring Tier-1 production lines.

Europe posts the highest forward CAGR due to unified safety laws and expansive smart-road investments. The EU's AEB mandate ensures uniform sensor installation across vehicle classes, while national road agencies deploy radar for congestion analytics. smartmicro UK surpassed 1,000 roadside units, illustrating integrator momentum smartmicro.com. Supply-chain reshoring counters semiconductor scarcity, and 5G corridors embed radar hand-in-hand with V2X beacons.

Asia-Pacific leads defense and weather spending. Japan's AN/SPY-7 roll-out and South Korea's L-SAM II project typify high-budget programs driving domestic GaN foundry growth. China's policy shift away from 24 GHz automotive radar accelerates migration to 77 GHz across local OEM plants. India's USD 50 million weather radar order demonstrates public-sector appetite for precision meteorology. Collectively, these initiatives expand the radar sensor market beyond consumer mobility.
