As an important signature of the radar target

the angular glint effects on radar system mainly arise at near field.However

the current prediction methods of angular glint are mostly based on the far field condition.This paper presents a prediction technique of near field angular glint based on the scatter-center model to solve this problem.Firstly

the near field backscattering is represented based on scatter-center model.Then by solving the derivative of the backscattering phase vs.the position vector of the observer

including incident angles and range

we get the exact expression of angular glint at near field.Finally

the exact expression is approximated and simplified in the range of terminal guidance.The conclusions of the paper show that the expression by HUANG Pei-kang in the book 'Radar Target Signatures’ is the approximation of ours at far field under certain polarization

and that the simplified expression has a well precision in the range of terminal guidance.All these results provide the theoretical basis for the prediction of near field angular glint and its signature research.
