Based on the moving target display(MTD)canceller model,the impact of the feedfor-ward and feedback branch parameters of the recursive cubic canceller on the MTD performance is emphatically analyzed,and the effects of different canceller coefficients on the notch width,pass-band flatness,and improvement factor are simulated and compared.The simulation test is conduc-ted to verify the effectiveness of the performance analysis,and the results show that the recursive cubic canceller can obtain better passband flatness,which is beneficial to improve the SNR of the signals to be detected.
