Assay of concurrent use of correlation and principal component analysis for tasks of UWB radar

The effectiveness of combining correlation of the signal reflected from the object with principal component analysis is investigated, for radar applications—in particular, ultrawide-band (UWB) bioradar systems such as remote contact-free detection and recording of human respiration. Simulation and physical experiments are employed. The signal/noise ratio for which it is advisable to use correlation of signal with reference signal is determined.
