FIELD: monitoring systems.
SUBSTANCE: invention relates to methods of security monitoring of the area and can be used in cases of signaling control of the crossing point of roads by one linear radio-wave detection means (DM). Proposed method consists in deployment at road intersection, where three roads converge in one DM according to scheme providing separation of useful signal with different depth and modulation mark at crossing security zone (SZ) by intruder: a signal in the form of a single negative ejection of a large modulation depth when a trespasser crosses a SZ near receiver (transmitter) or a signal in the form of a sequence of alternating positive and negative low modulation depths when crossing the middle of the SZ; and corresponding selection of three through roads converging in one through roads intersection of main through road, movement of intruder along which it is required to determine separately from two other secondary through roads; crossing the middle of the SZ of the agent (±10 meters) of the main through road, and its sections at a distance of not more than 10 meters from the receiver (transmitter) – secondary through roads, depending on their location relative to the main one.
EFFECT: possibility of determining the intruder motion along the main through road separately from the secondary through roads using only one DM at the intersection of roads.
