High resolution radar cross section imaging based on complex target backscattering simulation

Pixel method which is enlightened from the graphic electromagnetic computing (GRECO) is introduced in this paper and realized by OpenGL and VC programming. Using simulation data, the wideband features of the target can be obtained for radar automatic target recognition(RATR). Some of the calculated features including RCS, range profile, and SAR image which are also refered to zero-dimensional image, one-dimensional image, and two-dimensional image of the target are discussed in detail. Results show that the task of complex target backscattering simulation is effective for initial research and development(R&D) of radar automatic target recognition.
