Широкосмугова обробка акустичних сигналів безпілотніх літальних апаратів

Abstract

Antenna arrays are used in many applications where high gain and electrically variable radiation patterns are required. However, the main disadvantage of such antennas is their relatively narrow bandwidth. In this article, it is proposed to use time filters in the elements of the antenna array to generate frequency-dependent weights for processing acoustic signals emitted by UAVs.
