A New Technique for Measuring RCS at any Azimuth and any Distance in Near Field

Be satified with measurement requirement for target's characteristic RCS at any azimuth and any distance in near field,makes progress in extrapolation method study of RCS data based on target imaging measurement in near field.Experiments are carried out by imaging simulation data and actual measurement data with typical targets,which proves that the RCS method at any azimuth and any distance in near field is feasible and test data is effective.
