Description: 新三步搜索算法考虑了块矢量中心偏移的特性,在初步搜索时对中心周围的 位置同时做了匹配运算。在物体做小范围运动时,这种改进很有效,可以大大减少运算量,然而,在物体做大范围运动时,这种改进却带来了额外的运算量。现实的情况经常是物体既有小范围的偏移,也有大范围的运动。因此,在考虑块匹配算法时,既要照顾块的中心偏移特性,也要兼顾块的大范围运动。四步搜索 (Four-Step Search FSS)能够兼顾两种情况,可以得到较好的性能。 -The new three-step search algorithm to consider the block vector offset characteristics of the Center, in the initial search around the location of the center has done a matching operation at the same time. Done in small-scale movement of objects, this improvement is very effective, can greatly reduce the computational complexity, however, expand the scope of movement in the objects, this improvement has brought about additional computing capacity. Reality both objects are often small-scale migration, there are a wide range of movement. Therefore, in considering the block-matching algorithms, it is necessary to take care of the center block offset characteristics, but also take into account the large-scale block movement. Four-step search (Four-Step Search FSS) to take into account both cases, you can get a better performance.

Description: 波数域算法又称为距离徙动算法(Range Migration Algorithm,RMA)或-算法,由Cafforio等提出。该算法分析距离处理后信号的二维频谱,通过二维频域匹配滤波进行相位补偿,在完成方位聚焦的同时完全校正距离徙动。由于其中的Stolt变换能克服SAR信号中距离徙动和SRC对斜距的依赖,因此波数域算法是一种理想的成像算法,尤其在处理大斜视角和长合成孔径的SAR数据时。但Stolt变换需要插值,降低了处理效率并引入额外的误差。(The wavenumber domain Algorithm is also called Range Migration Algorithm (RMA) or -algorithm, which is proposed by Cafforio et al.The algorithm analyzes the 2-d spectrum of the signal after the distance processing, carries out phase compensation through the 2-d frequency domain matching filter, and completely corrects the distance migration while completing the azimuth focusing.Because the Stolt transform can overcome the SAR signal range cell migration and SRC dependence on oblique distance, thus wavenumber domain algorithm is an ideal imaging algorithm, especially when dealing with large squint Angle and long synthetic aperture of SAR data.But Stolt transformation requires interpolation, reduces processing efficiency and introduces additional errors.)
