摘　　要：针对复杂双基几何和轨道差异大等特性给高低轨双基地SAR构型设计带来的挑战,文中利用高低轨双基地SAR的几何关系,构建双基构型参数与成像性能间的数学模型,并建立了非线性多元的目标函数,将构型参数设计过程转化成非线性多元目标函数的优化问题,利用模拟退火算法进行求解。最后,通过仿真实验验证了该方法的有效性。Due to complex bistatic geometry and big differences of orbital characteristics,the configuration design of GEO-LEO BiSAR remains a challenge.To address the issue,mathematic models between these indicators related to the configuration parameters and the imaging performance are firstly derived based on the geometry analysis.Then,a general nonlinear multivariate equation is constructed based on desired imaging performance.Thus,the configuration design procedure is transformed to solve the nonlinear multivariate function.A new optimal method is presented based on simulated annealing(SA)algorithm.Finally,the simulation results verify the correctness of the presented method.
