I don't have specifics about this drone, but 77GHz radar units (used in cars) weigh in at a few ounces and can be configured for a range of over 100 meters. They could certainly detect small planes and would probably have little trouble with other drones as well. Kites and balloons at a distance might be a challenge - but they are slow moving.
