An Improved Back Projection Imaging Algorithm of Airborne Bistatic SAR
Author(s): 
Pages: 348-352
Year: Issue:  6
Journal: RADAR SCIENCE AND TECHNOLOGY

Keyword:  双基地SAR后向投影(BP)算法改进算法RD算法;
Abstract: 首先建立了机载双基地SAR的几何模型、距离历程和回波模型.接着简要总结了双基地SAR成像的算法思路.通过理论推导改进了单基地BP成像算法使其适合于双基地情况,并探讨了改进的快速BP算法.最后用点目标和面目标仿真验证了双基地下BP算法的有效性和适用性,并与RD算法进行了性能的比较.
