Abstract
The HF (high frequency) radar at Kodiak Island, Alaska, is part of the SuperDARN (Super Dual Auroral Radar Network) network of radars designed to detect echoes from ionospheric field-aligned density irregularities. Normal azimuth scans of the radar begin on whole minute boundaries leading to 12 s downtime between each scan. The radar makes use of this down time, by stepping through eight different frequencies for each beam direction using 1 or 2 s integration periods. A new receiver system has been developed at Poker Flat Research Range (PFRR), to utilize the ground scatter returns from radar's sounding mode of operation and calculate the ionospheric virtual reflection height. This would result in considerable improvement in the accuracy of critical frequency and Angle Of Arrival (AOA) estimations made by the Kodiak SuperDARN.
