Research of Echo Enhancement System of Passive Radar based on Variable Step Least Mean Square Algorithm

摘要：

In passive radar system based on noncooperative illuminator,since echo spectrum is covered seriously by direct path interference,adaptive echo enhancement system based on variable step Least Mean Square algorithm is introduced to remove direct path interference from polluted echo.In order to improve convergence rate,nonlinear function is proposed to change step with steady state error.Simulation turns out that adaptive echo enhancement system based on variable step LMS algorithm has rebuilt echo successfully in time and frequency domain with faster convergence rate.
