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.
