摘要：
Combined with the concept of angle pulse compression and the single model of SAR, a new method for angular super-resolution based on beam modulation is proposed. Based on the linear frequency modulate for beam scanning in azimuth direction, the analytic expression of the mapping relationship between angle and frequency is deduced. Then the unresolved targets in one pulse volume can be identified in range and azimuth directions by the range-azimuth control separately. The simulation results indicate that the proposed rule improve the multi-target resolution.
