| Abstract: | The performance of airborne radar strongly depends on the statistical distribution, the power spectral character and the fluctuation of the ground clutter. This paper presents a clutter modeling method using waveform synthesis theory in order to provide ground clutter simulation for analyzing airborne radar system. Compared with conventional modeling method that uses the distribution and power spectrum of clutter, this method can generate ground clutter data with a given distribution, power spectrum and fluctuation simultaneously. Comparison of simulation results and real radar clutter indicates that this method can model ground clutter of airborne radar more accurate than the conventional method. |
