Radar for the detection of aerial targets fitted on an aircraft, in particular for avoiding obstacles in flight

摘要

The device has an emission unit for emitting hyperfrequency waves in a direction towards an aerial target, where the waves have primary wave form (45) and impulsion type secondary wave forms. The primary wave forms are composed of two sinusoids (42-44) of different frequencies transmitted simultaneously. Reception circuits are arranged for receiving signals reflected from the target. An analyzing unit analyzes detection of the target from the received signals.
