Radar target attribute scattering center extraction method combining calculation and measurement data

A radar target attribute scattering center extraction method combining calculation and measurement data comprises the following steps: acquiring one-dimensional single-frequency sweep angle simulation data and two-dimensional sweep angle test data of a target, selecting the one-dimensional single-frequency sweep angle simulation data to calculate a time-frequency image, detecting a local scattering center according to Doppler frequency characteristics, performing IRT transformation on the time-frequency image, and extracting a target attribute scattering center according to the IRT transformation. The method comprises the steps of obtaining position information and amplitude information of a local scattering center LSC, performing one-dimensional peak detection on each row of a time-frequency image, setting a detection threshold value and a minimum DSC length of a distributed scattering center DSC, detecting and extracting DSC information, solving the accurate position of the DSC, and substituting the obtaine
