Abstract The beam of meter-wave radar is rather board, the exist of multi-path signals coherent with the direct arrival signal will cause badly affect to the altitude measurement, so it is more difficult for meter-wave radar to measure the altitude of the target. The general MUSIC algorithm is a super-resolution algorithm that can handle coherent signals, so it can be used in the height-finding of meter-wave radar. Based on the general MUSIC algorithm, a new algorithm for altitude measurement in the height-finding environment is presented. The new algorithm not only has a low computation complexity, but also has a good performance. Computer simulation results demonstrate the merits of the new algorithm.
