Based on the principle of interferometer angle measurement, an omnidirectional meter-wave radar antenna and its related angle measurement algorithms are provided in this paper. Unlike traditional large and poor maneuverable antennas, the new antenna had small size and simple structure, and the algorithms were simple and high accurate. In addition, the paper designed the algorithms' signal processing flow, and presented the simulation results of angle error on different SNRs, which proved the algorithms' effectiveness.
