Wideband interference suppression based on space-time filter

  • Received Date:2012-08-23
  • Based upon the diagonal loading technique and the structure of the space-time adaptive processors, a novel anti-jamming method of satellite navigation is proposed. According to matrix inverse theorem, the range of the diagonal loading values for space-time adaptive wideband signal processing structure is deduced, and the optimum equation of diagonal loading beam forming algorithm of space-time structure is obtained. Then, by the analysis of two-dimensional oriented vector in direction of the perturbation interference, the wideband interference covariance matrix obtained in the weights training period is modified. Finally, the optimum weight of multi-linear constrained space-time adaptive beam-forming alogrithm is derived for anti-interference filter processing. The new method effectively widens the null steering beams when discrepancy happens. The computer simulation results prove the robustness of the proposed method.
