Abstract:
This report investigates the possibility that meteor-nose echoes are a causative mechanism for noise currently being observed on the FPS-95 radar. A description of the noise is given as documented by on-site observers. Meteor- nose echoes are postulated as being partly responsible for the observed noise. Recent Madre Measurements have permitted a definition of the spectral character of the meteor-nose echo both in the near and far ranges. Spectral examples of each are given. The spectral behavior of the meteor-nose echo agrees very well with that of the FPS-95 noise. Theoretical tenets as well as experimental evidence force the conclusion that the FPS-95 noise is produced in part by meteor-nose echoes.
