摘　　要：在合成孔径雷达(SAR)成像算法中,波数域(ωk)算法是一种高精度成像算法,但是传统ωk算法并不能直接用于斜视情况。对传统ωk算法进行改进使其适用于斜视情况,首先对斜视SAR几何模型分析得到回波方程,然后对传统ωk算法改进得到斜视ωk算法,最后通过仿真实验,验证该算法的有效性和可行性。In the synthetic aperture radar(SAR)imaging algorithms,wave number domain(ωk)algorithm is an imaging algorithm with high precision,but the traditionalωk algorithm can’t be used in squint condition directly.This paper improves the traditional squintωk algorithm to apply to squint condition,firstly analyzes the squint SAR geometric model and obtains the echo equation,then improves the traditionalωk algorithm to get squintωk algorithm,finally verifies the effectiveness and feasibility of the proposed method through simulation experiment.
