摘要：
High resolution ultrasonic imaging may be achieved via the synthetic aperture focusing technique, provided that the synthetic antenna should be correctly spatially sampled, We show that a spatial undersampling is possible, using a digital spotlighting technique that permits to recover correct reconstructed images from the aliased data. The proposed method is applied to experimental ultrasonic data.
