ЧИСЛЕННОЕ МОДЕЛИРОВАНИЕ ОПРОСА РАДИОМЕТОК НА ПОВЕРХНОСТНОАКУСТИЧЕСКИХ ВОЛНАХ В СИСТЕМАХ РАДИОЧАСТОТНОЙ ИДЕНТИФИКАЦИИ С ПРИМЕНЕНИЕМ ЛЧМ-СИГНАЛОВ

The numerical simulation results of operating RFID system with SAW tags using LFM interrogation signal are presented. The particularity of the considered RFID system operation mode is the use of composite signal generated in the inquiry unit to interrogate SAW tag and the use of correlation processing when receiving tag response signal. This operation mode improves interference resistant and operating range of SAW RFID systems.
