ABSTRACT:
A precision azimuth angle and .+-. elevation angle of an emitter are determined by measuring the frequency and differential phase .psi..sub.j of a received signal at each of a number of interferometer rotational positions. Each measured differential phase corresponds to a set of possible cone angles satisfying
