Abstract :
The adaptive interference cancellation is the key factor in DTV based passive radar. The wide band of the DTV signal leads to the high computation burden and the decrease of the cancellation gain. To solve the two problems, an Adaptive filter with Discrete Distribution structure using NLMS algorithm(ADDNLMS) is proposed in this paper, which has better performance compared with the traditional NLMS filter. Moreover, it can adjust the weight structure according to the distribution of the clutters. Simulation and experiment data verification are carried out, which proves the efficiency of the proposed filter.
