Performance analysis between of Butterworth and Chebyshev filter for radar application / Noratika Mohammad Somari

In communication system, noise is one of the main factor that limit the capacity of data transmission on the accurateness of signal measurements. Noise is exists in communication channels and need to be recovered. This paper analyzed the performance of Butterworth and Chebyshev Filter in order to removed noise from radar signal. Simulated signal for three different frequencies (64MHz, 151MHz and 434MHz) are added with noise where signal to noise ratio is from OdB to 30dB. By applying different numbers of cut off frequency, the effectiveness of the filters has been analyzed. From the result, it can be concluded that Butterworth filter is suitable for radar application.
