How the airframes fly, how the sensors see, and how the layers fit together — written by the people who build them.
Radar PTZ integration hands a bearing from the drone detection radar to an EO/IR turret so it lands on the target on the first move. What the pointing budget, latency and hand-off protocol have to deliver.
Counter-UASA drone detection radar sees the aircraft; RF drone detection hears its link. Where each one wins, where each one is blind, and why a serious counter-UAS layer runs both.
VTOLRange, endurance and payload on a hybrid VTOL drone are a single trade curve. How lift-rotor drag, battery fraction and cruise speed set the number you can actually plan a mission around.
VTOLHand-launched fixed-wing, hybrid VTOL fixed-wing, or multirotor — how take-off method, range and payload decide the airframe for reconnaissance, mapping and ISR.
