Interferometric signal simulation based on fractal modeling

  • INSAR (interferometric synthetic aperture radar) signal simulation methods were investigated deeply, and the fundamental principle of the INSAR simulation was presented. Various noise interference factors in INSAR images were analyzed. The simulation model of the INSAR system was discussed in detail, which indicated that the precise model was very important for the INSAR simulation. Present general simulation models were compared and their disadvantages in INSAR simulation were also analyzed. Based on the self-affine fractal theory, the real interferometric process was simulated and the DEM (digital elevation model) satisfying space sampling rate was acquired. Results demonstrate that not only the stochastic properties and geometric distortion phenomena of ground targets,which are particular for radar interfermetry, are reflected vividly, but also the various distortion factors can be analyzed quantitatively. It is helpful to verify all kinds of interferometric arithmetics and optimize INSAR system design.
