| description | The invention, which belongs to the technical field of forward-looking radar imaging, in particular relates to a super-resolution imaging method of a forward-looking radar. According to the invention,an azimuth deconvolution model is constructed; and a singular value being obvious to noise amplification in an iterative process is found out from the perspective of the mathematics, so that the amplification transmission of the noise in the iterative process is suppressed. Therefore, the deconvolution has the better resolution performance in realizing radar super-resolution imaging.
本发明属于前视雷达成像技术领域，具体来说是一种前视雷达超分辨率成像方法。本发明通过构建方位向反卷积模型，从数学角度出发，找出在迭代过程中对噪声放大的较为显著的奇异值，达到了抑制噪声在迭代过程中放大传递的效应。使得反卷积在实现雷达超分辨率成像具有更好的分辨性能。 |
