摘要

The paper presents antenna arrays for a glide slope beacon of the instrument landing system. It proposes a procedure for building an antenna array with two subarrays, one of which radiates a Carrier plus sideband signal (CSB) and the second one radiates a Suppressed carrier sideband only (SBO) signal. The authors find the conditions, under which the information parameter of the beacon (the Difference in the depth of modulation, DDM) in the area of the Glide path coverage does not depend on the height of the antenna array relative to the underlying surface. Measurements made by an aircraft laboratory confirmed the stability of the glide path position when changing the height of the snow cover to 110 cm using the proposed antenna array.
