Problems solved by technology

[0007] At present, the existing TACAN field beacon simulator is limited to simulating the azimuth, distance and station identification signals of several fixed beacon stations in one channel, and can only provide one beacon station for airborne equipment at the same time The analog signal of the airborne equipment can only perform one-to-one performance testing with the airborne equipment, which cannot meet the needs of the airborne equipment for multiple beacons

Embodiment approach

[0047] The TACAN field beacon simulator radiates the TACAN analog beacon signal through the antenna, and also receives the interrogation signal of the on-board equipment through the antenna. From image 3 It can be seen from the block diagram of the TACAN field beacon simulator that the TACAN field beacon simulator is composed of three modules: a frequency synthesizer module, a microwave modulation module, a display control and a video processing module. The frequency synthesizer module and microwave modulation module are based on microwave signal processing and microstrip technology to complete the generation and reception of five-way radio frequency signals. The display control and video processing module is centered on the large-scale integrated circuit FPGA and high-speed single-chip MCU. On the one hand, it processes and displays the control information of the display control unit to form the Tacan video signal and azimuth envelope; on the other hand, it processes the rec...

Abstract

The invention discloses a tactical air navigation system external field beacon simulator, which consists of a frequency synthesizer module, a microwave modulation module and a display control and video processing module, wherein the frequency synthesizer module and the microwave modulation module finish generating and receiving five paths of radio frequency signals on the basis of microwave signalprocessing and a microstrip technology; the display control and video processing module takes a large-scale integrated circuit FPGA (Field Programmable Gate Array) and a high-speed MCU (Single Chip Microcomputer) as the center; and a bell shaped pulse and a PIN (Personal Identification Number) modulation technology are adopted to effectively improve frequency spectrum performance, and the full-frequency-band and full-channel coverage function of the tactical air navigation system external field beacon simulator is realized. A multi-channel parallel technology and the microwave modulation module with a microwave signal processing function are adopted to generate the simulation signals of a plurality of beacon stations, and a one-machine multiple-station function can be realized.

Description

Technical field: [0001] The invention relates to a tacan beacon simulation system, in particular to an outfield simulator with comprehensive beacon simulation functions such as tacan, DME ranging, DME (multiple) ranging and tacan (DME) positioning, etc., belonging to radio navigation field. Background technique: [0002] The Tacom beacon simulator is a special device used to calibrate, measure, and adjust the main technical indicators of airborne equipment. It truly simulates the azimuth and distance response signals emitted by the Tacom beacon station, and accurately provides the station for airborne equipment. It can identify signals and calibration indicators such as azimuth, distance, radio frequency level, etc. It can also simulate the rate of change of azimuth and distance, and has perfect control and test functions. According to different places of use, it can be divided into standard beacon simulator and TACAN outfield beacon simulator. The standard beacon simulator...
