ABSTRACT = {The Synthetic Aperture Radar (SAR) raw data generator is required to the 
evaluation of focusing algorithms, moving target analysis, and hardware design. The 
time-domain SAR simulator can generate the accurate raw data but it needs much time.
The frequency-domain simulator not only increases the efficiency but also considers the 
trajectory deviations of the radar. In addition, the raw signal of the extended scene
included static and moving targets can be generated by some frequency-domain 
simulators. However, the existing simulators concentrate on the raw signal simulation of 
the static extended scene and moving targets at uniform speed mostly. As for the issue, 
the two-dimensional signal spectrum of moving targets with constant acceleration can be 
derived accurately based on the geometric model of a side-looking SAR and reversion of 
series. And a frequency-domain algorithm for SAR echo signal simulation is presented
based on the two-dimensional signal spectrum. The raw data generated with proposed 
method is verified by several simulation experiments. In addition to reveal the efficiency 
of the presented frequency-domain SAR scene simulator, the computational complexity 
of the proposed method is compared with the time-domain approach using the complex 
multiplication. Numerical results demonstrate that the present method can reduce the 
computational time significantly without accuracy loss while simulating SAR raw data.},
