Market Overview

The Ground-Based Air Surveillance Radar Market will increase from 4,640 USD million in 2025 to 6.5 USD billion by 2035. During the forecast period (2025–2035), the ground-based air surveillance radar market's compound annual growth rate (CAGR) is anticipated to be approximately 3.4%.

The ground-based air surveillance radar market encompasses radar systems deployed on land, used to detect aircraft, drones, missiles and other aerial targets. These systems form the backbone of airspace situational awareness for military as well as civilian defence organisations. With increasing global tensions, the emphasis on real-time surveillance and early-warning capability has grown substantially. While the comprehensive data is proprietary to the referenced report by, key themes point to a steady rise in demand driven by strategic defence spending, technology upgrades and increased deployment of networked radar systems.

Growth Factors

Several forces are fuelling market growth. First, heightened defence budgets in many regions are enabling the acquisition and upgrade of radar infrastructure — reflecting the importance placed on air-domain awareness. Second, the proliferation of unmanned aerial vehicles (UAVs) and cruise missiles has challenged legacy radar networks, prompting investment in radars with enhanced detection range, target discrimination and multi-sensor integration. Third, the shift toward network-centric warfare and integrated defence ecosystems is encouraging the deployment of advanced ground-based radars that can feed data into wider command-and-control systems. These elements collectively bolster market momentum.

Trends Shaping the Industry

Several prominent trends have emerged:

  • Digitisation & Software Defined Radars: Modern GBASR systems are increasingly software-defined, enabling flexible upgrade paths and adaptation to new threats.
  • Multi-Functional and Multi-Domain Deployment: Radars are evolving to support detection of air, sea and even land targets from a single platform, reducing equipment footprint.
  • Cost-Effective Modular Solutions: To meet varied budget constraints, modular radar systems that can be scaled by mission requirement are gaining traction.
  • Integrated Sensor Networks: The trend toward fusing radar data with electro-optical/infra-red (EO/IR) sensors, command systems and other radars is strengthening comprehensive situational awareness.
  • Emerging Region Adoption: Many countries in Asia-Pacific, the Middle East and Africa are investing in ground-based air surveillance to fill gaps in local air-defence coverage.

Opportunities for Growth

The market offers compelling opportunities for vendors, integrators and defence-technology firms. For one, the upgrade cycle of Cold-War era radar systems presents a replacement opportunity. Moreover, as nations adopt “indigenisation” policies and partner with local firms (especially in Asia), there is scope for joint-ventures and localisation of production. Also, export potential remains robust for countries with advanced radar technologies, providing a pathway for expansion into allied defence markets. Finally, the integration of AI/ML into radar processing, and the incorporation of unmanned systems for remote or harsh-terrain deployment, offer new segments of growth.

Future Outlook

Looking ahead, the ground-based air surveillance radar market is expected to maintain healthy growth. Sustained defence spending, evolving threat landscapes (including hypersonic missiles and stealth UAVs), and the rising importance of airspace sovereignty will continue to drive demand. Vendors that invest in modularity, open-architecture systems and sensor-fusion capabilities will be well-positioned. Furthermore, regional diversification will be key: while mature markets remain important, emerging-economy defence modernisation programs will provide incremental growth. In essence, the next five to ten years appear to be a promising horizon for the GBASR market as air-surveillance becomes ever more essential in national security and defence strategy.
