7 FAQ （1）What is the angular accuracy of the SR-PA24R? The SR-PA24R is a 24GHz radar sensor is with one transmitter one reciever antenna, which can not be used to measure the angle of the target. （2）When SR-PA24R facing vegetation and ground/water surface when measuring... - Page 10 reference point is the ground or the water surface. If the aircraft fly above 5m, the airflow will not affect the vegetation below. If the vegetation density is high, then the detected height will be the distance from vegetation to the aircraft.
