This method can save the space of memory and reduce the computation time . because only the parameters of scattering centers are stored and genetic algorithm is used to search for aspect angle, the method is very suitable for the employment in real-time and restrictive environment . in chapter 3, the architecture of mmw seeker is studied 该方法以目标多散射中心理论为基础,只需要存贮目标的三维散射模型参数,需要的存贮量较少;与常规的全姿态角匹配识别方法比较,基于目标散射模型的匹配识别方法,由于利用了遗传算法的全局寻优能力,计算量较小。
