摘要
Abstract
To track the low elevation targetsusing array antenna,we have to mitigate the multipath effect.Based on the two-path multipath propagation models,the principle and constraint condition of symmetric beam mitigating multipath effect is studied,and a closed-loop tracking algorithm by improved symmetric beam constructed by difference beam phase toggling in two pulse periods is devel-oped.Results of simulation indicate that the proposed method can improve the angle resolution of the beam and the multipath error is im-proved obviously.关键词
