摘要
常用的RD算法对斜视角限制较严,而且RCMC插值较为复杂,降低了算法的效率。针对这一缺陷提出了在方位向分块处理的改进RD算法,从而提高了处理效率,改善了大斜视角对RD算法的限制,并通过计算机仿真以及实测数据验证了改进的RD算法的可行性。
The restriction of common RD algorithm to the squint angle is strict,and the RCMC interpolation is more complicated and lower the efficiency of algorithm. Considering this blemish,put forward an improved RD algorithm based on divisional disposal at azimuth,so raised a processing efficiency thus and improved the restriction of the squint angle to the RD algorithm,and identify the possibility of improved RD algorithm by computer imitation and actually data.
