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. %K General MUSIC algorithm %K Direction-of-arrival %K Coherent source %K Meter-wave radar %K Height-finding
