We report the analysis of a peculiar signature present in Signal to Noise Ratio (SNR) plots from meteor-head radar returns. These radar reflections were collected with the High-Power Large-Aperture (HPLA) radar at Jicamarca in Lima, Peru. The signature appears to be systematic, being caused by the combined effect of meteor-head echoes properties and signal processing in the radar receiver. We describe a first order model to support this hypothesis. Our studies reveal that at least 15% of the
