Abstract:

The Verona Ava Linear Array Radar VALAR is a high resolution experimental HF backscatter data acquisition system designed to investigate the characteristics of high latitude auroral clutter. The transmit system located in Ava, New York, is capable of providing RF signals in the 2-30 MHz band with up to 300 kW average power. The receive system at Verona, New York, consists of a 72 element linear antenna array extending 700 meters in length and 36 identical HF receivers. Since the completion of system test and calibration at the end of 1989, data acquisition campaigns have been carried out on a near monthly basis. In this paper we provide a brief description of VALAR and present some examples of initial results from the preliminary analysis of HF aurora backscatter data acquired during 1990. These examples demonstrate the capability of VALAR as a high resolution HF backscatter data acquisition system.
