Why AESA radar is superior to PESA radar?
The vast number of different tactical radar systems and their applications can be overwhelming. However, most tactical systems rely on one of two main technologies — passive or active electronically-scanned arrays. Before investigating the advantages and disadvantages of PESA radar vs. AESA radar, let’s discuss the basics of how radar sensors work.…

Active Electronically Scanned Array (ASEA) Radar
What is Active Electronically Scanned Array Radar (ASEA)? Active Electronically Scanned Arrays are considered a phased array system, which consists of an array of antennas which form a beam of radio waves that can be aimed in different directions without physically moving the antennae themselves. The primary use of AESA…

Evolution of Airborne Electronically Scanned Array Radar
For many decades, one of the main characteristics of most land, sea, and airborne radars was the use of a moving antenna. Mechanical movement was needed either to survey an area of terrain, sea or sky, or to direct the radar to a specific target. In the case of airborne…
