Embodiment Construction

[0041] The following content will describe in detail the specific implementation of the present invention in conjunction with the accompanying drawings:

[0042] The testing device in the prior art determines whether the testing equipment is qualified or not by analyzing the unmodulated video signal. The real signal of the Tacan system is 950MHz~1213MHz, and only through the detection of radio frequency signals can we accurately locate whether the tested equipment is qualified or not;

[0043] The present invention introduces radio frequency technology, with the help of NI RF vector signal generator PXI-5670 and NI RF vector signal analyzer PXIe-5663 (including downconverter, digitizer and mixing signal generator), it realizes the direct acquisition of ground station simulation RF signals sent and received by the transmitter.

[0044]The workflow of the Tacon calibration system is divided into receiving and transmitting. The receiving process is mainly to receive the azimuth ...

Abstract

The invention provides a Tacan simulator metering device and a Tacan simulator metering system. The device adopts a radio frequency technique to directly acquire radio frequency signals transmitted and received by a Tacan simulator of an earth station; the system comprises modules such as a level measuring module, a modulation degree measuring module, a direction measuring module, a direction velocity measuring module and the like, and is used for achieving calibration of a direction signal of the Tacan simulator and the calibration of a ranging signal.

Description

Technical field: [0001] The invention belongs to the technical field of radio short-distance navigation, and specifically relates to a measurement method and device of a Tacan simulator. Background technique: [0002] In the early days, if the air navigation wanted to determine the position of the aircraft, it was necessary to use two or more ground navigation stations, and the positioning accuracy was very low. Such positioning technology did not have much practical value. Therefore, in the middle of the 20th century, in order to achieve precise air positioning and navigation, the Tacan system was developed by the Federal Telecommunications Laboratory of the United States based on the suggestions of the US Air Force and Navy. Tacan's original name is TACAN, which is the abbreviation of Tactical Air Navigation System-tactical air navigation system. It is a short-range radio navigation system. short-range radio navigation system. In the 1950s, it was first applied to the ca...
