| 摘 要： | 针对单部窄带雷达无法获得高速自旋目标无失真二维像的问题,研究了基于多部窄带雷达组网的自旋目标无失真成像方法。首先在建立自旋目标窄带雷达回波模型基础上,分析了单基窄带雷达成像方法;然后分别研究了基于多幅窄带雷达图像配准的旋转对称目标和非旋转对称目标图像二维定标方法;最后,对配准后的各窄带雷达图像进行融合得到了目标的无失真二维像。仿真实验验证了本文方法的有效性,并分析了算法的鲁棒性。

| 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. |
