Based on the application of adaptive filtering technology in ground-based surveillance radar signal processing, a method of real-time estimation of clutter spectrum parameters by autocorrelation and adaptive control of filter based on statistical parameters is proposed. By using threshold decision method, The spatial distribution of airspace and the error introduced by the target in the estimation of the parameters of the clutter spectrum.In this paper, the application of adaptive filtering technology is discussed in detail.The theoretical analysis and simulation show that the method is correct and feasible Finally, combined with engineering practice, given TMS32020 digital signal processor to achieve clutter spectrum parameter estimation and adaptive control scheme for the program.
