In this paper, we proposed an adaptive generalized displaced phased center antenna (AGDPCA) algorithm for clutter suppression in airborne radar from a viewpoint of a two-dimensional pulse-to-pulse canceller. First, the clutter model and signal model are given in matrix-vector form, and this leads naturally to the design of a two-dimensional (2-D) two-pulse (2-P) canceller and the GDPCA algorithm formulation. Second, the AGDPCA algorithm is developed by dynamically estimating the 2-D 2-P canceller from the received data. Third, the 2-D 2-P canceller is extended to 2-D multi-pulse canceller to improve the moving target detection performance in AGDPCA algorithm. The effectiveness of the proposed methods is tested via several experiments.
