Abstract :
The sufficient and necessary condition of using the two-dimensional (2D) Fourier method for simulating SAR raw signals is given. Some important issues when implementing squint stripmap SAR echo simulation are discussed such as slow-time baseband conversion and circular interpolation. Simulation results for an artificial scene and an actual scene demonstrate its validity and effectiveness.
