By parting the target to very small size cells, using high-frequency approximation, the near-field radar cross section （RCS） is calculated based on the scattering from complex targets and environments （SCTE） system, and the angular glint is calculated by the phase grads. The results show that the angular glint can be calculated exactly in the SCTE system, and this method is correct and efficient. In the near-zone, the far-field theory is not applicable and the angular glint should be calculated by the near-field theory.展开更多

文摘This paper presents a method to analyze and calculate the angular glint of targets. By parting the target to very small size cells, using high-frequency approximation, the near-field radar cross section （RCS） is calculated based on the scattering from complex targets and environments （SCTE） system, and the angular glint is calculated by the phase grads. The results show that the angular glint can be calculated exactly in the SCTE system, and this method is correct and efficient.
