Abstract:
High-frequency (HF) radars take advantage of long-distance multiple-hop propagation that is possible in the HF band. At large distances, ionospheric targets become overspread or susceptible to range-Doppler ambiguities (long range: > 1000 km and high velocity: ~1 km/s). Ionospheric radars, such as the Super Dual Auroral Radar Network (SuperDARN) radars employ the multiple-pulse technique to overcome these ambiguities at the expense of introducing self-clutter. The present study utilizes measurements of echo power to estimate self-clutter, which can be used to provide signal-derived estimates of the mean square error in radar observations.
