Detecting moving target based on reflectivity displacement method and wavelet transform

The reflectivity displacement method is one of the generally used methods to detect the moving target in the SAR system. However, in low signal-noise ratio (SNR) environment, it is still difficult to estimate the moving target's parameters correctly. To improve the estimating performance, wavelet transform is adopted as a further processing step to eliminate the noise of graphs obtained from the reflectivity displacement method in this paper. Simulation results demonstrate that it is effective to estimate the parameters of the moving target with the method proposed.
