Anti-jamming Method of Sliding Window QR Decomposition Based on Hyperbolic Givens Rotation

Impulsive jamming is difficult to be suppressed by traditional QR decomposition method. A sliding window QR decomposition array processing method based on hyperbolic GIVENS rotation was proposed. The input data with sliding window method can adjust adaptive weights more quickly to time-varying jamming than traditional recursive QR methods. This algorithm has high numerical stability and a modular structure, making it easy for hardware implementation. The simulation results verify that this method outperforms the QR method in the case of pulse jamming.
