A novel approach of moving target localization based on the focused imaging is proposed for the problem of "azimuth position uncertainty" in the single-channel SAR (Synthetic Aperture Radar).According to the deduced relationship between moving target and azimuth antenna pattern
the approach uses the relative endpoints of moving target Doppler spectrum to estimate moving target parameters
which can locate the moving target precisely.This approach with lower computation load can be used in lower signal to clutter ratio
which is easy to realize and has wide applications.Both simulation and real data experiments illustrate the effectiveness of this approach.
