Abstract:

An existing computer program which is called the roll plane program was modified. This modification made possible the calculation of the direction of arrival angle from an emitting source. The simulation of a detection scheme which was mounted on an aircraft was a three-element antenna array. Through phase shifting techniques in this array the direction arrival angle was calculated.
