APRIL 7 AOC VIRTUAL SERIES WEBINAR: Active vs Passive Electronically Scanned Antennas
1400-1500 EDT (1800-1900 GMT)
In the early 1970s, electronically scanned antennas (ESAs) emerged as a new and impactful technology for ISR missions. Replacing mechanically scanned antennas (MSAs), ESAs were much faster for beam switching from a mission timeline perspective, and eliminated the size weight and power associated with a gimbal. As ESAs became better understood, passive EW modes were added as part of their capability offering. This highlights the revolutionary impact of ESAs on the warfighter battlespace.
This talk will show the genesis from MSA to passive ESA to active ESA and provide a conceptual understanding of the advantages of an active ESA. Additionally, the talk will show how the next ESA transformation that is currently taking place is from analog active ESAs to digital active ESAs.
