Signals Intelligence SIGINT Market

Signals Intelligence Market Size

The global signals intelligence market was valued at USD 16.8 billion in 2024 and is estimated to register a CAGR of over 5.4% between 2025 and 2034.

This is driven by the rapidly improving AI and sensor technology. Since AI-based algorithms can analyze massive amounts of data, at high speeds, allowing quicker signal processing, and faster automated identification of threats. Augmented with machine learning, which enables systems to detect patterns and anomalies in adversary communications and electronic emissions.

Advances in sensor technology, such as increased sensitivity and enhanced filtering of signals, have made SIGINT platforms range and accuracy in orders of magnitude higher. These advances have decreased the need for human operators and facilitated more accurate intelligence collection, both strategically and tactically, in those settings.

In September 2024, Ukrainian firm Infozahyst showcased its Archon signals intelligence (SIGINT) system, it is available in stationary and mobile versions and utilizes a radio direction-finding network to intercept enemy signals without the enemy realizing that their signals are being captured.

The rise in geopolitical tensions, military confrontations, and regional disputes have made SIGINT very important for national defense.  Many countries are utilizing it to monitor the movement of their enemies and gain a significant edge on the opponent. There is an increasing worry about electronic warfare (EW), and SIGINT is being used to counter jamming, spoofing, and other militarily antagonistic electronic threats. The Ukraine conflict, constant strife in the Indo-Pacific, and the multiple security emergencies in the Middle East and Africa showcase even more the importance of SIGINT systems in modern warfare.
