本文提出了 Omega-k SAR 处理算法的傅立叶解释，有助于解释关键的 Stolt 映射操作。有时会使用该算法的近似形式，我们将解释两种形式的 ωKA 如何与距离多普勒和线性调频缩放算法进行比较。最后，简要讨论了哪些雷达参数允许准确使用每种算法。
This paper presents a Fourier interpretation of the Omega-k SAR processing al- gorithm that helps explain the key Stolt mapping operation. An approximate form of the algorithm is sometimes used, and we explain how both forms of the ωKA compare with the range Doppler and the chirp scaling algorithms. Finally, a brief dis- cussion is given on which radar parameters allow the accurate use of each algorithm.
