The detection of moving targets on synthetic‐aperture radar images is one of the most popular approaches to monitor ground vehicles and ships on an ocean. Although the well‐known displaced phase centre antenna (DPCA) or along track interferometry (ATI) has good detection performance, they often produce high false alarm rates. A new scheme, i.e. a moving target indicator (MTI) using the sequential combinations of DPCA and ATI to reduce the number of false alarms is suggested. The simulation results show that the proposed MTI scheme can provide a low false alarm rate, while maintaining good detection performance.
