Abstract

The research reported in this paper is related to the ultra-wide-band radar technology that may be employed in care services for the elderly. Two algorithms for preprocessing of measurement data from an impulse radar sensor are compared with respect to the uncertainty of estimation of echo parameters. These are: an algorithm based on curve-fitting in the spectrum domain and a modified CLEAN algorithm. Preliminary results of numerical experiments performed on those algorithms are demonstrated.
