Abstract :
The noise in the radar data results in the flutter of the flight target in display screen, which may disturb observer. A rounding method for radar target track using Butterworth filter is proposed in this paper. With the spectrum characteristics of radar target track being analyzed, the filter´s parameters can be designed and figured out. Therefore, after the noise in radar signal is magnified by a transformation algorithm, it can be smoothed online. The results of MATLAB illustration show that the method has a reliable denoising performance.
