Abstract:

It is unable to get a distortionless image of high-speed spinning targets with single narrow-band radar. To solve this problem, an undistorted imaging method based on narrow-band radar networks is studied. Firstly, after establishing the echo model of spinning targets, the monostatic narrow-band radar imaging method is analyzed. Then two-dimensional image scaling methods for rotational symmetry and unsymmetrical targets are studied respectively, via registering the multi-images from different narrow-band radars. Finally, the undistorted target image is obtained by fusing the registered images from different narrow-band radars. By simulations, the validity of the proposed method is verified, and the robustness is also analyzed.
