摘要
Abstract
In this paper, an ISAR imaging simulation method combined with graphical electromagnetic computing (GRECO) technique is introduced. The electromagnetic scattering data of maneuvering targets is obtained by using of GRECO. The radar echo of maneuvering targets is got by transmitting linear FM signal and an ISAR imaging of simulated echo is carried out. Different from point target simulation, 3D target simulation and imaging is very similar to the reality and is more suitable for application and imaging effects analysis and stuay of algorithm improvement and anti-interference. The scattering field of target surface is analyzed based on high frequency predict theory and is calculated based on the physical optics (PO) method and physical theory of diffraction (PTD). The ISAR images can be obtained with different motion compensation methods and reconstruction algorithms. The simulation results of complex target show that the method has the characteristics of correctness, effectiveness, and real-time performance.关键词
