Summary:This paper presents an improved clutter removal technique using comb-notch FIR filter. In conventional non-recursive and recursive clutter removal approach, the range profile could not be detected in presence of strong clutter response while target is slowly moving. This approach is capable to remove clutter responses with a 20 dB improvement factor. The experimental data is recorded for indoor and outdoor environment using S-band FMCW radar and the proposed clutter removal technique is applied. According to the experimental validation, this technique is more capable to remove clutter responses while adequately preserve the signal coming from moving target.
