METHOD AND RADIO SYSTEM FOR IDENTIFYING AIRCRAFT Russian patent published in 2015 - IPC G06F1/00 G06F21/00 

FIELD: radio engineering, communication.

SUBSTANCE: method is carried out by inputting identification code information of identified objects into the differential time offset of noise-like signals used as request and response signals. The system consists of an identifier placed on an aircraft and a ground-based identification device. The main parts of said devices are correlation meters for determining the differential time offset of noise-like signals used for identification.

EFFECT: high security of the identification owing to invariance to interception of confidential information, high noise-immunity of the system.
