The study aims to increase amplitude direction-finding sensitivity for radio monitoring. The methodology utilizes a TSA antenna and a phase-antiphase divider to form dual radiation patterns. Results confirm high accuracy and signal processing speed. The originality lies in combining a compact design with an innovative processing algorithm. Practical value is demonstrated by a small-scale UAV-integrated finder capable of intercepting ultra-weak signals for reconnaissance and EW. The paper establishes a universal approach to high-efficiency mobile defense systems with low power consumption.
