Airborne Synthetic Aperture Radar (SAR) Multi-Point Target Echo Signal Simulation and Range-Doppler (RD) Imaging Simulation

Airborne Synthetic Aperture Radar (SAR) is a widely used remote sensing technology capable of acquiring high-resolution images of ground targets. During multi-point target echo signal simulation, we can model the echo signal characteristics of different targets to better understand and analyze their scattering properties through signal generation algorithms that typically involve calculating phase histories, range compression, and incorporating platform motion effects. Furthermore, for Range-Doppler (RD) imaging simulation, we can simulate the working principles of radar systems and signal processing algorithms, implementing key functions such as range cell migration correction (RCMC), azimuth compression, and Doppler parameter estimation to obtain target imaging results. These simulation studies enable us to enhance the performance of airborne synthetic aperture radar in target detection and imaging applications, providing more possibilities for remote sensing applications through systematic testing of various imaging scenarios and algorithm optimizations.
