The paper performed the survey and selection of structural parameters of the CIC filter (Cascade Integrator Comb) in the design process of the radar demodulation system on Matlab software. The demodulation system input signal is a reflected pulse signal from the target modulated in 3 forms: Baker code, linear frequency modulation (RF), and M code (spurious signal code or binary encoding). The impact noise is assumed to be white noise. The results of the study and survey give a specific assessment of the dependence of the side beam level and the width of the main beam output signal on the selected frequency band.
