Abstract :
In radar receiver system, the wavelet and wavelet packet transform can be used to improve the Radar Anti-jamming Performance. By using this method, given a threshold value to remove the components of the noise and the rest of the wavelet coefficients can be used to reconstruct signal, thereby reducing the impact of the noise. Simulation results showed that, for 30MHz radar signal, the optimal level of transform decomposition is 3, and the wavelet transform can improve the Radar Anti-jamming Performance better.
