摘要
The strong attenuation of high frequency electromagnetic wave widens the radar wavelet and lowers its resolution. The attenuation of high frequency can be described by a specifically defined quality factor. The resolution was improved and the dispersion was removed by inverse Q filter designed by electromagnetic wave propagation equation. It has been proved that inverse filter has clear effect for removal dispersion and improving resolution by processing synthetic and real data.
