SPECIFIC FEATURES OF SINGLE- POSITION RADIOACTIVE DETECTION DEVICES

This article studies the technical characteristics of modern perimeter security systems and the effectiveness of their use. The study analyzes the principles of operation of single-position radio-beam detection devices (BRAT) based on the Doppler effect, their advantages in mobile systems, and spatial stability problems. The article also examines the specific characteristics of coaxial cable sensors with a waveline (ChTL) and infrared (IR) sensors, their interference resistance, and installation schemes in various terrain conditions. The technical characteristics of devices such as “LUCh-M”, “ABRIS” and “SIKLOP-30” for detecting an intruder are studied in a comparative manner, and the factors that cause the systems to malfunction (metrological conditions, electromagnetic interference) are identified.
