N2 - In accordance with the problem that it is difficult for radar simulator to load massive broadband frequency sweep data, this paper proposes an approach for extracting the wideband radar targets' scattering center parameters to reduce the storage requirement of frequency sweep data and solve the efficiency and precision problem of loading data. Firstly, resampling is conducted to echo signal in order to ensure uniform sampling of data. Then, the wideband scattering center model is transformed into statespace equations in order to estimate the location information of the scattering center through the simplified singular value decomposition (SSVD) and the spectrum estimation. Finally, the intensity of scattering center is calculated based on the maximum likelihood estimation method. The effectiveness of the approach is verified by computer simulation and it can provide a reference for the dynamic loading of simulator.
