After analyzing the characteristics of multi-aperture moving targets detecting and imaging

the paper improves the classical displaced phase center antenna (DPCA) measurements.The improved algorithm detects moving targets through pictures interpolation and pictures registering when using two apertures.Moving targets parameters can be estimated and at the same time moving targets images can be obtained if aperture number is increased.The blind speeds can also be removed.In the last

some typical computer simulation results are presented which illustrate the methods' validities.
