Abstract

Abstract:

For the distributed coherent aperture radar (DCAR), the precondition to realize fully coherent mode is phase synchronization. However, DCAR phase synchronization is influenced unfriendly owning to grid mismatch filtering, strong maneuverability with ceil radars, posture changes and so on. To solve that, a UAV DCAR phase synchronization error estimation method based on prominent scatterers is proposed. It takes advantage of the polynomial iteration method firstly to eliminate phase residual due to grid mismatch filtering, after which it implements DCAR posture compensation in accordance with inertial navigation system information. Then the Taylor estimation method is proposed to estimate the position error, and other phase errors can be derived by utilizing the self-correcting method. Finally, the DCAR system could realize calibration to accomplish phase synchronization. The numerical examples demonstrate the validity of the theoretical results.

Key words: distributed coherent aperture radar (DCAR), phase synchronization, grid mismatch, polynomial iteration, Taylor estimation, position error
