Their new technology is described like this:
"Echodyne is hard at work on our next product release — a complete MESA based radar at K-band specifically designed for Airborne Detect and Avoid (DAA) for small UAS [unmanned aircraft systems]. While final specifications are not being released, MESA-DAA is based largely on MESA-K-DEV. Package size and weight are planned to be appreciably less than MESA-K-DEV — especially if the unit is placed inside the sUAS airframe. Range is planned to be >3KM with scanning speed of 1Hz for the entire field of view and as fast as 10Hz for updating locations of previously detected objects. The field of view for a single unit is planned to be ±60° in azimuth (120° total) and ±40° in elevation. Multiple units can be combined if greater field of view is desired."
I expect it will only be a couple of more years before we see package and other delivery systems operating in the commercial space. Already I'm reading about different government organizations starting to use drones in their work.
