Abstract

Abstract

Along-Track Interferometry (ATI) or Displaced Phase Centre Antenna (DPCA) technique can be applied to detect ground moving targets for airborne and space-based radars. As the first step of data processing, co-registration of the data received from different channels is necessary. In this paper, a new algorithm of data co-registration is proposed. Firstly, the received data is co-registered coarsely according to radar parameters measured primarily. Then in order to improve the co-registration accuracy further, time lag is estimated precisely via phase compensation idea based on the received data in range-Doppler domain. This algorithm does not require interpolation operation, therefore reducing the processing burden. The simulation results demonstrate that this algorithm can meet the real-time co-registration requirement.
