Abstract
In order to achieve the target azimuth detection, this paper uses magnetic measurement azimuth on the basis of laser ranging. A rotary scanning magnetic dipole model was established and the target-azimuth solution was achieved using a periodic-phase detection algorithm. Combining magnetic dipole model and target azimuth solution method, the influence of the distance between the sensor and the magnetic core, the rotation scanning detection period, the signal detection threshold and the standard deviation of the probability density of noise signal on the statistic distribution of azimuth measurement are analyzed. The accuracy of azimuth detection is studied by numerical simulation and measurement experiment.
