Strategy Analytics: AESA Architectures Catalyzing $21.5 Billion Military Radar Market

AESA (active electronically scanned array) architectures enabled using GaN (gallium nitride) and GaAs (gallium arsenide) semiconductor technologies will increasingly underpin radar systems and serve to catalyze military radar market growth through 2027. Strategy Analytics Advanced Defense Systems (ADS) service series of forecasts covering the global military radar market detail global expenditure as well as system shipments across the land, air, sea and space domains. Summarized in Military Radar Market Outlook 2017-2027, Strategy Analytics projects the global military radar market will grow at a CAGR (compound annual growth rate) of 4.6% over the 2017 to 2027 forecast timeframe to be worth over $21.5 billion.

Suppliers of military radar systems are increasingly implementing AESA architectures at the core of their product offerings highlighting advances in performance as well as lifecycle and total cost of ownership advantages over traditional radar designs.

An AESA radar comprises a large number of transmit-receive modules that feed and collect multiple signals via an antenna array. Potential advantages of an AESA architecture include high beam steering agility, very low radar signature when illuminated and extremely low side lobes. Being able to digitally control transmit-receive module gain, allows for refined power management which is vital for reduced or low probability of intercept (RPI, LPI) operation. In addition, AESA architectures enable software programmability that can provide progressive refinements in overall radar system performance.

From an operational perspective, the implementation of AESA architectures in military radar systems enables improvements in system reliability and reductions in total cost of ownership. The use of multiple transmit receive modules (TRMs) means that even if a proportion of the TRMs fail, the radar itself can continue to function (referred to as graceful degradation) and be operated, with repairs effected alongside the scheduled downtime of a platform. This ensures mission continuity as well as imparting cost of ownership and operational cost benefits to the end-user.

“AESA architectures have typically been GaAs-based, but the increased power, efficiency and robustness offered by GaN is being adopted by the defense industry across land-, air- and sea-based military radar systems,” noted Asif Anwar, Director of the ADS service. “Needless to say, this does not mean that GaAs technology will no longer be used, any more than it would be unwise to suggest that there will no longer be demand for vacuum tube based RF transmitters. However, GaN is able to displace both GaAs (and other RF semiconductors) as well as vacuum tube technologies, which is why we’ll see military radar demand for GaN growing the fastest, with a CAGR of 19.0% through 2027.”
