防空与飞弹防御雷达市场－全球产业规模、份额、趋势、机会、预测：按平台、雷达类型、应用、地区和竞争格局划分，2021-2031年

全球防空和飞弹防御雷达（AMDR）市场预计将从 2025 年的 79.8 亿美元成长到 2031 年的 117.2 亿美元，复合年增长率为 6.62%。

该领域涵盖专门用于识别、追踪和分类空中威胁（包括弹道飞弹和无人驾驶航空器系统）的侦测系统。市场成长的主要驱动力是日益加剧的地缘政治不稳定和高速飞弹技术的快速发展，迫使各国对其国防基础设施进行现代化改造。根据航太工业协会（AIA）预测，到2024年，美国航太和国防出口预计将达到1,386亿美元，凸显了全球对安全相关技术的巨大需求。

儘管市场潜力巨大，但由于先进雷达组件的研发和整合成本高昂，市场成长面临许多挑战。向有源电子扫描阵列技术的过渡涉及复杂的製造工艺，推高了单位成本，并常常给国家采购预算带来压力。此外，关键半导体相关的供应链瓶颈持续存在，可能导致生产进度延误，从而影响这些关键国防系统的及时供应和作战准备。

市场驱动因素

先进高超音速和弹道飞弹的威胁日益加剧，各国政府为应对速度超过5马赫且飞行轨迹难以预测的武器而采取的应对措施，是推动市场发展的主要动力。传统雷达系统往往缺乏监测这些高机动性威胁所需的灵敏度和处理速度，因此，采用氮化镓（GaN）技术的下一代主动电子扫描阵列（AESA）架构正在兴起。大规模采购计划清楚地表明了这项技术需求。例如，根据RTX在2025年9月报道，美国陆军授予雷神公司一份价值17亿美元的合同，用于生产低空防空反导感测器（LTAMDS），该系统旨在对抗先进高超音速武器。此类投资凸显了能够同时追踪360度范围内复杂空中目标的雷达的重要性。

同时，不断增长的全球国防预算和军事开支是这些耗资巨大的现代化计划的重要资金来源。东欧和印太地区日益加剧的不稳定局势终结了冷战后财政紧缩的时代，导致各国政府大幅增加国防费用以弥补能力不足。根据斯德哥尔摩国际和平研究所（SIPRI）2025年4月发布的报告，2024年全球军事支出达到创纪录的2.718兆美元，较去年同期成长9.4%。随着各国更加重视空中主权，这一增长直接支持了战略感知能力建设的资金投入，例如，根据《外交官》杂誌2024年12月报道，日本防卫省在其2025年预算中特别拨款约34亿美元，用于加强其综合防空反导（IAMD）网络。

市场挑战

持续的供应链中断，尤其是与关键半导体相关的供应链中断，是限制防空和飞弹防御雷达市场成长的主要障碍。先进的雷达系统，特别是采用主动电子扫描阵列（AESA）技术的雷达系统，高度依赖精密微电子元件的稳定供应。当这些关键元件的供应受限时，製造商将面临不可避免的生产延误，从而阻碍现有合约的及时履行。无法准时交付成品系统会导致收入延迟到帐和订单累积，直接阻碍市场扩张。

这种依赖程度之高，从支撑整个产业的供应商网路所创造的巨大经济价值可见一斑。根据美国航太工业协会（AIA）统计，2024年美国航太和国防供应链创造了约4,390亿美元的间接经济效益。这个庞大网路中的任何中断，例如半导体短缺，都可能引发连锁反应，导致关键国防资产的部署停滞，进而限制全球航空航太、国防和研发（AMDR）市场的整体发展。

市场趋势

随着军事组织努力简化后勤需求并提高作战灵活性，向多任务、多模式能力的转变正在从根本上改变市场格局。各国不再使用独立的感测系统执行广域搜索、火力控制和反炮兵任务，而是越来越多地采用能够同时执行这些不同功能的软体定义架构。这种整合实现了动态资源管理，并减少了远征部队所需的硬体库存，因为单一雷达单元即可侦测弹道飞弹并同时追踪低空空中威胁。为了满足对灵活整合资产的需求，洛克希德马丁公司于2024年9月宣布，挪威国防材料局已行使购买选择权，增购三部TPY-4地面多用途雷达，以增强其综合威慑网路。

同时，为了应对无人机群和短程炮弹带来的非对称威胁，无人机小型化及其与战术平台整合的趋势正在加速发展。传统的高功率监视雷达往往过于固定，无法满足快速战术性机动的需求，因此，市场对可安装在装甲车辆和移动式短程防空（SHORAD）平台上的紧凑型轻量化感测器的需求日益增长。这些小型化系统采用高频段，能够在复杂环境中精确追踪低雷达反射面积目标，以保障地面部队的安全。这种转变在近期的采购趋势中显而易见；例如，2024年7月，亨索尔特公司宣布已订单一份价值1亿欧元的订单，将专门为SkyRanger 30移动式防空坦克提供SPEXER防空雷达。

The Global Air and Missile Defense Radar (AMDR) Market is projected to expand from USD 7.98 Billion in 2025 to USD 11.72 Billion by 2031, reflecting a CAGR of 6.62%. This sector comprises specialized sensing systems engineered to identify, track, and categorize aerial dangers, including ballistic missiles and unmanned aerial systems. The market's upward trajectory is largely fueled by increasing geopolitical volatility and the rapid advancement of high-speed missile technologies, which are forcing nations to update their defense infrastructures. As reported by the Aerospace Industries Association, U.S. aerospace and defense exports hit $138.6 billion in 2024, underscoring the strong worldwide demand for security-focused technologies.

Despite this potential, market growth faces significant hurdles due to the exorbitant costs involved in researching, developing, and integrating advanced radar components. The shift toward active electronically scanned array technologies entails intricate manufacturing processes that raise unit costs, frequently stretching national procurement budgets. Furthermore, ongoing supply chain bottlenecks related to essential semiconductors can retard production timelines, thereby hindering the timely supply and operational activation of these critical defensive systems.

Market Driver

The escalation of advanced hypersonic and ballistic missile threats acts as a major market accelerator, as countries strive to neutralize weapons that exceed Mach 5 and possess unpredictable flight paths. Conventional radar systems frequently lack the necessary sensitivity and processing velocity to monitor these agile threats, driving a transition to next-generation Active Electronically Scanned Array (AESA) architectures utilizing Gallium Nitride (GaN). This technological necessity is highlighted by significant procurement initiatives; for example, RTX reported in September 2025 that the U.S. Army granted Raytheon a $1.7 billion contract to initiate production of the Lower Tier Air and Missile Defense Sensor (LTAMDS), a system engineered to counter sophisticated hypersonic weaponry. Such investments emphasize the vital need for radars capable of engaging complex aerial targets simultaneously across a 360-degree horizon.

Simultaneously, the worldwide rise in national defense budgets and military spending supplies the essential funding to support these costly modernization projects. Increasing instability in Eastern Europe and the Indo-Pacific has concluded the period of post-Cold War fiscal restraint, leading governments to significantly boost defense spending to address capability deficiencies. According to the Stockholm International Peace Research Institute (SIPRI) in April 2025, global military expenditure hit a record high of $2,718 billion in 2024, marking a 9.4 percent increase in real terms from the prior year. This fiscal expansion directly supports increased funding for strategic sensing capabilities as nations focus on air sovereignty, evidenced by The Diplomat's December 2024 report that Japan's Ministry of Defense allocated roughly $3.4 billion specifically to bolster its Integrated Air and Missile Defense (IAMD) network in the 2025 fiscal budget.

Market Challenge

Ongoing supply chain interruptions, particularly concerning vital semiconductors, represent a significant obstacle to the growth of the Air and Missile Defense Radar market. Advanced radar systems, especially those employing active electronically scanned array technology, rely heavily on a consistent supply of sophisticated microelectronics for operation. When the availability of these key components is limited, manufacturers encounter inevitable production setbacks that hinder the timely execution of existing contracts. This failure to deliver completed systems on time directly impedes market expansion by delaying revenue realization and leading to an accumulation of backlogs.

The extent of this reliance is demonstrated by the considerable economic value generated by the supplier network that supports the industry. As stated by the Aerospace Industries Association, the supply chain for the U.S. aerospace and defense sector created approximately $439 billion in indirect economic activity in 2024. Any disruption within this extensive network, such as a semiconductor deficit, triggers a chain reaction that halts the deployment of essential defense assets, thereby constraining the overall progress of the global AMDR market.

Market Trends

The transition toward multi-mission and multi-mode capabilities is fundamentally transforming the market as military forces aim to streamline their logistical requirements and enhance operational versatility. Instead of utilizing distinct sensing systems for volume search, fire control, and counter-battery tasks, nations are increasingly adopting software-defined architectures capable of performing these varied functions concurrently. This integration permits dynamic resource management, enabling a single radar unit to detect ballistic missiles while simultaneously tracking low-altitude aerial threats, thus lowering the hardware inventory needed in expeditionary forces. Reflecting this demand for flexible, consolidated assets, Lockheed Martin announced in September 2024 that the Norwegian Defence Materiel Agency exercised an option to acquire three more TPY-4 ground-based multi-mission radars to strengthen its comprehensive deterrence network.

At the same time, the trend toward miniaturization for UAV and tactical platform integration is accelerating to counter the asymmetric danger posed by drone swarms and short-range projectiles. Conventional high-power surveillance radars are frequently too static for rapid tactical movements, leading to a rise in demand for compact, lightweight sensors that can be mounted on armored vehicles or mobile short-range air defense (SHORAD) platforms. These scaled-down systems employ high-frequency bands to deliver accurate tracking of targets with small cross-sections in complex environments, providing security for mobile ground units. This shift is illustrated by recent procurement actions; for instance, Hensoldt reported in July 2024 that it received an order valued at nearly 100 million euros to provide SPEXER air defence radars specifically for the mobile Skyranger 30 anti-aircraft gun tank.
