Introduction

The electronically scanned array (ESA) market is experiencing significant growth, fueled by rising demand for advanced radar and communication technologies in defense, aerospace, and commercial sectors. According to Stratview Research, ESA systems are increasingly replacing traditional mechanically scanned radars due to their superior performance, flexibility, and reliability.

According to Stratview Research, The electronically scanned array market size was US$ 8.6 billion in 2024 and is likely to grow at a strong CAGR of 7.5 % in the long run to reach US$ 17.8 billion in 2034.

Key Features

Electronically scanned arrays use electronic beam steering instead of mechanical movement, allowing rapid tracking of multiple targets. Key features include higher resolution, faster response times, reduced maintenance needs, and resistance to mechanical wear. Modern ESAs also support multifunction capabilities—combining surveillance, communication, and electronic warfare within a single platform. Their scalability across different frequencies makes them adaptable for both military and civilian applications.

Applications

In defense, ESAs are widely used in fighter aircraft, naval ships, and ground-based radar systems for surveillance, missile guidance, and threat detection. The aerospace sector employs ESAs for air traffic control and weather monitoring. Civil applications include satellite communication, automotive radar for driver assistance, and space exploration. The growing integration of ESAs in unmanned aerial vehicles (UAVs) further highlights their expanding role.
