[Abstract]:The strabismus Spotlight synthetic Aperture Radar (SAR) is applied to the imaging of ship targets at sea. Based on the variation of squint angle, multiple high-resolution microwave images of the same ship with different oblique angles can be obtained by strabismus sliding spotlight SAR at high frequency, which is beneficial to the classification and recognition of ship targets. The high efficiency imaging algorithm of squint sliding spotlight SAR is combined with the (ISAR) refocusing algorithm of ship target inverse synthetic aperture radar (SAR). The imaging processing experiments are carried out against the computer simulation data, and good imaging results are obtained. The advantages of multiple high-resolution images can be obtained at high frequency when strabismus gliding spotlight SAR is applied to ship target imaging.
