In this paper, we introduce a method of using angular phase information of radar echo amplitude signal to do angle super resolution. The theoretical analysis and the principle of its resolution are given and it is proved that this method is feasible. The simulation shows that when the signal to noise ratio is 10dB is still effective to distinguish whether it is multi-objective.The paper also simulates the time-function mismatch between the time function of the antenna main lobe and the radar echo amplitude, indicating that under certain conditions, the target can still be effectively resolved. Finally, the experimental results of actual radar data are given, which shows that this method is feasible in practice.
