Based on the echo model of SAR, An advanced SAR raw data frequency-domain simulation method is introduced, and the time-frequency-domain simulation method of SAR raw data based on complex scenarios is presented. The formulae of the advanced SAR raw data frequency-domain simulation are deduced in detail, and the process of the complex scenario raw data simulation is shown. The results and conclusions of the simulation experiments show that the advanced SAR raw data time-frequencydomain simulation method can greatly improved the speed and accuracy of the simulation. The results and conclusions also manifest the validity of the complex scenario raw data simulation method.
