Abstract
CFAR (Constant False Alarm Rate) detectors were designed and evaluated in non-homogeneous DVB-T (Digital Video Broadcasting-Terrestrial) passive radar scenarios. The CA-CFAR (Cell-Averaged CFAR) is the most widespread incoherent CFAR technique. CA-CFAR detector is optimal under the assumption of homogeneous interference, but CA-CFAR performance is degraded when this assumption is not fulfilled. As an attempt to design CFAR algorithms in non-homogeneous environment, VI-CFAR (Variability Index-CFAR) was proposed. CA-CFAR and VI-CFAR detectors were designed and evaluated in a simulated and real passive radar scenarios. The real data were acquired by IDEPAR demonstrator, a DVB-T passive radar system. Results confirm the suitability of VICFAR based solutions in passive radar scenarios providing detection probabilities much higher than the detection capabilities associated with CA-CFAR.
