AESA Radar and Its Applications Training
AESA Radar and Its Applications Training Course – Hands-on
AESA Radar and Its Applications Training, participants will learn why the AESA radar has become the system of choice on modern platforms by understanding its capabilities and constraints, and how these capabilities and constraints come about as a result of the AESA approach. While offering performance that is inherently superior to conventional systems, AESA radar is technologically and architecturally more complex. This AESA Radar and Its Applications Training course will then proceed to describe in details several key surface and airborne radar applications who have been used in traditional radar systems, but whose performance is enhanced by the AESA class of radar. Essential support technologies such as antenna auto calibration, antenna auto compensation, and radar modeling and simulation will also be covered.
