Abstract

In order to improve the angle precision of minitype antenna, an algorithm of angle measurement based on orthogonal dipole antenna is introduced in this paper. In this algorithm, target's incidence angle is obtained by measuring the phase error of the left-hand rotation polarization signal and the right-hand rotation polarization signal. Then the method of resolving angle-measuring ambiguity is also presented. Last, the relation of angle measuring precision and involved factors, including SNR, channel amplitude error, and antenna orthogonal error is analyzed. Simulation results indicate that our algorithm can obtain high angle measuring precision, and has good detection capability of omni direction. Besides these, antenna structure is simple, and easy to install and maintain. It has certain engineering application practical value.
