摘　　要：电磁散射数据是目标识别研究的基础,但由于试验测量成本高、可重复性差等问题,空中目标电磁散射实测数据十分有限。基于去遮挡的N点模型和电磁计算数据插值研究了空中目标动态电磁散射数据仿真方法,设计了空中目标动态电磁数据仿真系统,该系统将电磁散射仿真与实际飞行场景相结合,支持场景自定义和空中目标三维模型库扩展。分析了飞机和巡航导弹2类目标仿真数据及成像结果,结果验证了仿真方法正确性和系统有效性,可为研究实际场景下的空中目标识别提供支撑。Electromagnetic scattering data is essential for the recognition of targets.However,due to issues such as high cost and poor repeatability of experimental measurements,the quantity of measured electromagnetic scattering data of targets is very limited.A dynamic electromagnetic scattering data simulation method for air targets was studied based on the N-point model with hidden points removed and electromagnetic caleulation data interpolation.Additionally,a dynamic electromagnetic scattering data simulation system for air targets was designed.This system integrated electromagnetic scattering simulation with actual flight scenes and supported scene definition and expansion of 3D models for air targets.Simulation data and imaging results of aircraft and cruise missiles were analyzed.The results show that the simulation method is correct,and the system is effective.The system can support the research on the recognition of air targets in actual scenes.
