Abstract

FIELD: radio engineering, particularly, systems of type "interrogator-responder" and to signalling systems responding to passive reradiation. SUBSTANCE: objects for use of proposed system can be people, objects or devices. System may be used for search for people covered by avalanche, for inspection of presence or absence of object at appropriate place, for surveillance signalization, specifically to prevent carrying away of unpaid goods from train halls and so on. Radio engineering system to search for and inspect objects equipped with passive responders incorporates interrogator 1 composed of two transmitted 2 and 3 of interrogation signals with proper transmitting antennas 4 and 5, receiver 6 of responses with receiving antenna 7 and passive responders 8. Each of them has receiving oscillatory circuit 9, nonlinear element 10 and transmitting antenna 11. Output of receiver 6 of interrogator 1 is connected to signalling device 12. EFFECT: enhanced authenticity of operation of system by exclusion of false operation caused by parasitic harmonic components of signal spectrum irradiated by transmitter of interrogator. 1 cl, 2 dwg

Радиотехническая система для поиска и контроля объектов, снабженных пассивными ответчиками, относится к радиотехнике, в частности к системам типа запросчик-ответчик и системам сигнализации, реагирующим на пассивное переизлучение. Объектами применения предлагаемой системы могут быть люди, предметы или устройства. Система может быть использована для поиска объектов, в частности для поиска людей, засыпанных лавинами, для контроля наличия или отсутствия объекта на месте, для охранной сигнализации, в частности для предотвращения выноса неоплаченных товаров из торгового зала и т.д. Цель изобретения - повышение достоверности действия системы путем исключения ложного срабатывания, обусловленного паразитными гармоническими составляющими спектра сигнала, излучаемого передатчиком запросчика. Радиотетническая система для поиска и контроля объектов, снабженных пассивными ответчиками, состоит из запросчика 1, содержащего два передатчика 2 и 3 сигналов запроса со своими передающими антеннами 4 и 5, приемник 6 ответных сигналов с приемной антенны 7 и пассивных ответчиков 8, каждый из которых содержит параллельно соединенные между собой приемный колебательный контур 9, нелинейный элемент 10 и передающую антенну 11. Выход приемки 6 запросчика 1 соединен с устройством сигнализации 12. 2 ил.

A radio engineering system for searching and monitoring objects equipped with passive transponders relates to radio engineering, in particular to interrogator-transponder systems and signaling systems that respond to passive re-radiation. The objects of application of the proposed system can be people, objects or devices. The system can be used to search for objects, in particular, to search for people covered with avalanches, to control the presence or absence of an object on the spot, for the security alarm, in particular to prevent the removal of unpaid goods from the trading floor, etc. The purpose of the invention is to increase the reliability of the system by eliminating false triggering due to spurious harmonic components of the spectrum of the signal emitted by the transmitter of the interrogator. The radio test system for searching and monitoring objects equipped with passive transponders consists of an interrogator 1 containing two transmitters 2 and 3 of the request signals with its transmitting antennas 4 and 5, a receiver 6 of response signals from the receiving antenna 7 and passive transponders 8, each of which contains a receiving oscillating circuit 9, a nonlinear element 10, and a transmitting antenna 11 connected in parallel to each other 11. The receiving output 6 of the interrogator 1 is connected to an alarm device 12. 2 ill.
