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. In the near-zone, the far-field theory is not applicable and the angular glint should be calculated by the near-field theory.

“…Swanson constitutive model could described the phenomenological constitutive relationship about the correlativity between the temperature and the strain rate of the solid propellant, it has been widely used in the solid motor engineering projections. It is difficult to determined the strain-softening function and the change strain rate correction function for Swanson constitutive model, which restricted its application [1][2][3][4][5][6].…”

Establishing Swanson constitutive model is discussed for composite solid propellant, which focused on the calculation of strain softening function and change strain rate correction function within the model. Prediction results of Swanson constitutive model are in good agreement degrees with the test of 24 groups uniaxial tensile data of composite solid propellant at different temperatures and extension rates. It proves the model is effective and available.
