Direction Determination		■
The angular determination of the target is determined by the directivity of the antenna. Directivity, sometimes known as the directive gain, is the ability of the antenna to concentrate the transmitted energy in a particular direction. An anfpnna with hinh Hirpptiv/it\/ ic alen rallpH a	N 0°

By measuring the direction in which the antenna is pointing when the echo is received, both the azimuth and elevation angles from the radar to the object or target can be determined. The accuracy of angular measurement is determined by the directivity, which is a function The True Bearing (referenced to true north) of a radar target is the angle between true north and a linę pointed directly at the target. This angle is measured in the horizontal piane and in a eloekwise direction from true north. The bearing annlp to thp rariar tarnpt mau olcn ho mpacurpri in a	s 270°	90°
