A new method based on joint pixel interferograms is proposed for three-channel ground moving target indication (GMTI).Firstly
a joint probability statistical model is established using the statistical properties analysis of multilook SAR interferograms after joint pixel processing.Then the false and leak alarms are analyzed.Meanwhile
considering the velocity ambiguity in the range of minimum detectable velocity (MDV)
an energy center method is presented to resolve ambiguity.Lastly
the interferometric magnitude and unambiguous phase are jointed to detect moving targets.The validity of new detection method is demonstrated by the results from real data.
