Techniques for Doppler Spectral Estimation of HF Radar Signals Backscattered from High Latitude Ionospheric Irregularities.

Abstract

This report examines various techniques for studying the Doppler spectrum of radar signals backscattered from high latitude ionospheric irregularities, Both pulsed and FM-CW techniques are considered and it is found that most approaches suffer from the need to have sufficiently high pulse or sweep repetition frequencies while at the same time avoiding range aliasing of the backscattered signals.
