According to our (Global Info Research) latest study, the global Signals Intelligence (SIGINT) market size was valued at US$ 15230 million in 2024 and is forecast to a readjusted size of USD 21160 million by 2031 with a CAGR of 4.8% during review period.

Signals intelligence (SIGINT) is intelligence-gathering by interception of signals, whether communications between people (communications intelligence—abbreviated to COMINT) or from electronic signals not directly used in communication (electronic intelligence—abbreviated to ELINT). Signals intelligence is a subset of intelligence collection management.

Global Signals Intelligence key players include BAE systems, Northrop Grumman, L3 Technologies, etc. Global top three manufacturers hold a share about 30%. United States is the largest market, with a share about 30%, followed by Europe and China, both have a share over 35 percent. In terms of product, COMINT is the largest segment, with a share about 45%. And in terms of application, the largest application is Airborne, followed by Space.

The driving factors of the signal intelligence (SIGINT) market mainly include the following points:

1. Changes in the global security situation

Terrorist threats: With the increase of global terrorist activities, the demand for security intelligence by governments has also increased, which has promoted the development of the SIGINT market. SIGINT can collect and analyze signals from communications and electronic equipment of terrorists, providing key intelligence for counter-terrorism operations.

Inter-state competition and conflict: The tension of international relations and the continuous regional conflicts have made countries pay more attention to intelligence collection. As an important means of intelligence collection, the market demand for SIGINT has also increased.

2. Increase in defense budget

Military modernization needs: In order to maintain national security, major countries in the world have increased their defense budgets for military modernization and equipment upgrades. As an important part of modern military equipment, the research and development and production of SIGINT systems have received more financial support.

Defense system update: With the continuous advancement of technology, aging defense systems need to be updated to cope with increasingly complex threats. The update and upgrade of SIGINT systems is also an important part of it.

3. The promotion of technological progress

The development of sensor technology: The continuous advancement of electronic sensor technology enables the SIGINT system to collect more accurate and comprehensive information. This improves the effectiveness of the SIGINT system and also promotes the development of the market.

Improvement of data processing capabilities: The rapid development of big data and artificial intelligence technologies has enabled the SIGINT system to efficiently process and analyze large amounts of signal data, improving the accuracy and timeliness of intelligence.

IV. Development of commercial aerospace

Expansion of commercial satellite services: With the rapid development of commercial aerospace, the field of commercial satellite services has continued to expand. As an important part of commercial satellite services, the market demand for SIGINT services has also increased.

The rise of spaceborne radio monitoring: Spaceborne radio monitoring uses low-orbit small satellites to monitor the spectrum from space, breaking through the national boundaries and geographical barriers of spectrum monitoring. This technology has the advantages of wide coverage and high positioning accuracy, and has become an important driving force for the SIGINT market.

V. Support from policies and regulations

Government attention to intelligence work: Governments of various countries have attached increasing importance to intelligence work, and have issued relevant policies and regulations to support the research and development and application of SIGINT systems. This provides a good policy environment for the development of the SIGINT market.

International cooperation and exchanges: International cooperation and exchanges have also promoted the development of the SIGINT market. Countries have improved the effectiveness and level of SIGINT systems by sharing intelligence resources and technological achievements.

In summary, the driving factors of the signal intelligence (SIGINT) market mainly include changes in the global security situation, increases in defense budgets, the promotion of technological progress, the development of commercial aerospace, and the support of policies and regulations. These factors have jointly promoted the rapid development of the SIGINT market.
