FPGA TACAN TACAN Interrogater based on FPGA

摘要

An FPGA-based TACAN interrogator is disclosed. A TACAN (Tactical Air Navigation) interrogator installed in an aircraft according to an embodiment of the present invention is designed based on a Field Programmable Gate Array (FPGA), and a transmitter that transmits an interrogation signal to a TACAN transponder of a ground station, a ground station A receiver for receiving a signal including a response signal to the interrogation signal from the TACAN responder, a distance calculator for calculating the distance between the ground station and the aircraft based on the time difference between the transmission time of the interrogation signal and the reception time of the response signal, and the received signal It may include an azimuth calculator for calculating an azimuth between the ground station and the aircraft based on the phase difference between the predetermined frequency signal and the reference signal extracted from the .
