A fast microwave correlated imaging method based on strip division in large scenes

A fast correlated imaging method based on strip division in large scenes is proposed. By transmitting narrow-pulse random signals synchronously from random radiation radar array, the whole imaging area is divided into multiple strips in range direction, then correlated imaging model in strip mode is established, which reduces the scale of its imaging matrix equation greatly; By multi-strip stitching, a whole correlated imaging in a large scene can be achieved; Numerical simulations validate its effectiveness in reducing its imaging time dramatically meanwhile improving its image quality.
