Rapid association imaging method and device based on strip segmentation and data fusion

The invention provides a rapid association imaging method and device based on strip segmentation and data fusion. The method comprises steps of enabling antenna radiating units of a radiation array synchronously to emit space-time orthogonal and independent random narrow pulse signals, and dividing the imaging area in the oblique downward view direction of the antenna radiation array into a plurality of strips; interacting the space-time random radiation field formed in each strip with the corresponding observation target to form the pulse echo of each strip; dividing each pulse echo into a plurality of echo range gates and echo sub-gates, and performing sampling in a specific echo sub-gate within each echo range gate to obtain multiple groups of echo sampling values; constructing and solving the associated imaging equation of each strip by using the v random radiation field and the corresponding echo sampling value of each strip, and obtaining the imaging result in the area of the each strip; and selecting the image fusion method to make the adjacent strip smooth transition, and obtaining the whole inversion result of the imaging area The correlation imaging equation for a single strip of each treatment of the present invention is small in scale, enabling rapid imaging.
