Abstract

The present invention provides a method and device for spatial compound imaging. The method comprises steps of receiving a component image C(i, j), where i denotes a steering scan cycle, and j a steering angle of the component image; computing a differential image by subtracting a component image C(i−1,j) from the component image C(i, j) with the same steering angle from a previous steering scan cycle; pre-processing said differential image; compounding the pre-processed differential image and a previous compounded image to form a new compounded image.
