Twenty-Element Receive Array for the Doppler Arrival Angle Spectral Measurements Experiment. Instrumentation papers,

Abstract

The report describes the twenty-element receive-only antenna array to be used in the DAASM (Doppler-Arrival Angle Spectral Measurements) experiment to be conducted at Goose Bay, Labrador, Canada. The twenty elements are configured to provide both a twelve element 'filled' array, of spacing 10 or 20 m, and a 'minimum redundancy' array composed of eleven elements and having equivalent aperture of 450 m. The effective 'beams' for both types of array are described mathematically, with some reference to their well-known applications in radio astronomy. The minimum redundancy array permits greater resolution; but phase information is lost and a beam cannot be formed instantaneously, as in the case of a filled array. (Author)
