Abstract :
The paper has realized radar echo receiving and adaptive clutter cancellation to non-cooperative passive radar based on FM broadcast illuminator. The preferences methods including of filter order, initial value of filter coefficients and step size are given. And improved method of variable step size is proposed. The experiment of simulation data and detecting data indicate: it has enhanced system stability while convergence rate is improved, and it is helpful to adaptive cancellation for slow time variable system
