倾斜面阵下的米波雷达测高方法

Abstract

Abstract: The algorithms available assume the vertical linear form array model, but the oblique planar array, which brings the mutual coupling between azimuth and elevation, is used in the VHF radar system in actual application. In order to decrease the effect of multipath propagation and mutual couplings under the oblique planar array, the temporal-spatial sequential Maximum Likelihood algorithm is extended to estimate the two-dimension angle for the oblique planar array, which not only avoids the effect of the multipath, but also decreases the mutual coupling by two-dimension scanning and the altitude root mean square error is less than 1％ of the range. Simulation shows the effectiveness of the method.

Key words: array, altitude measurement, multipath propagation, couplings
