Three-Dimensional (3D) And Four-Dimensional (4D) Military Radars Market Global Report 2026

The three-dimensional (3d) and four-dimensional (4d) military radars market size has grown strongly in recent years. It will grow from $10.93 billion in 2025 to $11.83 billion in 2026 at a compound annual growth rate (CAGR) of 8.2%. The growth in the historic period can be attributed to growing demand for real-time military surveillance, increasing modernization of defense radar infrastructure, rising adoption of phased-array radar technology, increasing focus on battlefield situational awareness, growing demand for accurate target detection and tracking.

The three-dimensional (3d) and four-dimensional (4d) military radars market size is expected to see strong growth in the next few years. It will grow to $15.99 billion in 2030 at a compound annual growth rate (CAGR) of 7.8%. The growth in the forecast period can be attributed to rising demand for next-generation multifunction radar systems, increasing deployment of high-frequency radar technologies, growing adoption of gallium nitride radar components, rising demand for enhanced low-observable target detection, and increasing integration of advanced electronic warfare capabilities. Major trends in the forecast period include increasing adoption of active electronically scanned array radar systems, growing demand for advanced digital beamforming capabilities, rising use of gallium nitride-based radar transmitters, increasing development of multifunction radar systems, and growing demand for high-precision target detection and tracking.

The rising military expenditure worldwide is expected to propel the growth of the 3D and 4D military radars market in the coming years. Military expenditure refers to government spending on armed forces, defense equipment, military operations, research and development, and other defense-related activities intended to maintain national security and military readiness. Military expenditure is increasing due to rising geopolitical tensions, prompting nations to allocate larger defense budgets toward strengthening military preparedness, modernizing armed forces, and improving national security capabilities. The growth in military expenditure supports the development and adoption of 3D and 4D military radars by enabling increased investment in advanced radar technologies that improve air surveillance, target detection, missile defense capabilities, and battlefield situational awareness. For instance, in April 2025, according to the Stockholm International Peace Research Institute (SIPRI), a Sweden-based independent international institute, global military expenditure reached $2.72 trillion in 2024, representing a 9.4% increase in real terms compared with 2023. Therefore, the rising military expenditure worldwide is driving the growth of the 3D and 4D military radars market.

Major companies operating in the 3D and 4D military radars market are focusing on developing innovative solutions such as 4D multi-mode radar systems to enhance multi-domain surveillance, drone detection capabilities, target tracking accuracy, and border security operations. 4D multi-mode radar systems are advanced electronic scanning array (ESA)-based radar technologies that provide three-dimensional target information, including range, direction, and altitude, along with an additional dimension such as target movement characteristics or velocity analysis, enabling more accurate detection and classification of complex threats compared with traditional radar systems. For instance, in June 2026, Blighter Surveillance Systems, a UK-based radar technology company, received a follow-on contract from an undisclosed Eastern European Army to supply Blighter A800 Mk 2 4D Multi-Mode Radars for protecting vulnerable land and sea borders against ground incursions and low-flying drones. The radar system integrates advanced Ku-band sensing, electronic beam scanning, monopulse elevation measurement, and micro-Doppler signature analysis to simultaneously detect, classify, and track ground, maritime, and aerial targets at ranges of up to 20 km. The system is designed to identify challenging low-altitude threats, including small drones with low radar cross-sections, through sophisticated clutter suppression technologies and AI-assisted software integration. The radar solution also incorporates BlighterNexus software to connect with command-and-control networks and third-party sensors, providing a unified operational view for enhanced battlefield awareness.

In May 2025, Thales S.A., a France-based provider of 3D and 4D military radars, partnered with Tawazun Council to establish a local production facility for Ground Master air surveillance radars in the United Arab Emirates. Through this partnership, Thales S.A. and Tawazun Council aim to strengthen the UAE’s defense manufacturing capabilities by locally producing, assembling, testing, and qualifying advanced Ground Master air surveillance radars, while enhancing national self-sufficiency, developing local industrial capabilities, and fostering Emirati talent in advanced radar technologies. Tawazun Council is a UAE-based government entity responsible for advancing the country’s defense and security industry.
