An efficient direct data domain STAP scheme based on a sparse reconstruction of the primary data is presented to effectively detect ground moving targets.To reduce the computational complexity
the proposed method obtains the high resolution angle-Doppler spectrum by finding the sparsest coefficients using the reduced-dimension data in element-Doppler domain.Therefore
based on the distinct image features of clutter and targets signals
a knowledge-aided moving targets detection algorithm is also introduced.The effectiveness of the proposed approach is shown by both theoretical analysis and simulation results.This scheme is computationally efficient for real-time parallel processing.
