Simulation on the Seeker Signal Wavelets Denoising Based on Parameters Optimization

The corrupted seeker signals are filtered by using the denoising technology of wavelets thres-hold,and the simulations are performed in off-line denoising pattern and real-time denoising pattern.Under the off-line denoising pattern,the useful signals,which coincides with the real generated angular velocity,can be obtained in the circumstances of heavy noise through optional optimization of the denoising parameters.Under the real-time denoising pattern,considering the comlexity of the algorithm to constrain the denoising parameters,the simple denoising parameters are taken selectively.After denoising,the promotion of PSNR is more than 5dB.This study shows that this method can overcome the limitations of traditional seeker denoising technology and can provide the maintenance for the design of the seeker's filters.
