摘要
提出了一种基于ChirpScaling(CS)算法的机载前斜视合成孔径雷达(SSAR)的成像处理实现方法。这种算法由于避免了插值运算,且能够精确地进行距离徙动校正,故使得成像质量等于或好于经典的距离-多普勒(RD)算法。该算法只需通过复乘和PFT就能够实现成像处理。
In this peper,a airborne squint synthetic aporture radar(SSAR) imaging processing al-gorithm suing chirp scaling(CS)algorithm is presented.The CS algorithm avoids interpolation,yet performs range cell migration correction accurately,so it provides image quality results eqwual or better than the preci-sion rang/Doppler(RD)algorithm, The algorithm requires only complex mulitiplies and fast Fourier trans-forms to implement.
