摘要
电大尺寸目标快速三维成像仿真在完成目标在弹目交会成像仿真坐标系的转换后,采用成像算法取代频率逐点扫描和散射数据逆傅里叶变换成像算法,直接获得目标时域响应,采用单双站近似法提高角度扫描的计算速度,从而实现导弹类电大尺寸目标三维快速成像仿真,仿真速度提高约两个数量级。
A fast simulation method for 3D Image of electromagnetic large target is proposed. Firstly, the target is transformed to the coordinate of missile target encounter. Image-domain method is used to acquire the target's time-domain response, and monostatie-bistatic equivalentce us used to save the computation time. Using the fast scheme, a speed gain of a factor of 100 is achieved for the missile target.
