Abstract
A radio navigational device for determining the angle of a mobile craft by analyzing the signals arriving at each element of a linear array of n equally spaced elements. A series of received R.F. pulses emanating from the mobile craft by transmission or reflection provide contemporaneous signals at the antenna elements with a phase difference .psi. between successive elements in accordance with the angle of arrival of the R.F. pulses. Using 'zero' IF techniques, each signal of the series is processed to provide signal outputs in I and Q form. Sequential or parallel sampling of these I and Q signals provides a synthesized scanning beam signal from which .psi. is determined.
