Embodiment Construction

[0016] The specific embodiment of the present invention will be further described below in conjunction with accompanying drawing:

[0017] refer to figure 1 , a Tacan simulator based on PXI synthetic instruments, including a computer for generating baseband signals, the output of the computer is sequentially connected with a modular vector signal generator, a circulator and a modular vector signal analyzer, the The output end of the modular vector signal analyzer is connected to the trigger signal input end of the modular vector signal generator, and the circulator is also connected with a bidirectional fixed attenuator. The two-way working gain of the two-way fixed attenuator is 40dB, and the other input and output end of the two-way fixed attenuator serves as a communication port between the Tacan simulator and the airborne equipment.

[0018] Further as a preferred embodiment, the modular vector signal generator includes an IQ signal generator and an upconverter connected ...

Abstract

The invention discloses a PXI synthetic instrument-based TACAN simulator. The PXI synthetic instrument-based TACAN simulator is characterized in that the PXI synthetic instrument-based TACAN simulator comprises a computer for producing baseband signals; an output end of the computer is orderly connected to a modular vector signal generator, a circulator and a modular vector signal analyzer; an output end of the modular vector signal analyzer is connected to a trigger signal input end of the modular vector signal generator; and the circulator is connected to a bidirectional fixed attenuator. The PXI synthetic instrument-based TACAN simulator adopts a synthetic instrument technology and utilizes a universal PXI modular instrument as a hardware platform. The computer in the system can manage and control the modular instrument by a PXI bus. The computer writes a software algorithm so that a TACAN simulator software module is formed. Compared with the existing desktop TACAN simulator, the PXI synthetic instrument-based TACAN simulator has the advantages of small volume, light weight, strong functions, high cost-performance ratio, and high maintainability. The PXI synthetic instrument-based TACAN simulator can be widely used in the field of aircraft airborne equipment detection.

Description

technical field [0001] The invention relates to a Tacan simulator, in particular to a Tacan simulator based on a PXI synthesis instrument. Background technique [0002] TACAN, also known as Tactical Air Navigation System, is a military tactical air navigation system developed to adapt to shipboard and mobile stations. It is a polar coordinate positioning system composed of supporting ground beacon stations and airborne TACAN equipment. At present, mainstream military aircraft at home and abroad are equipped with this system, and it will be used as one of their important navigation devices for a long time. The development of aviation technology requires the maintenance of airborne equipment to keep up with the pace. The traditional Tacan test equipment is a desktop instrument. The Tacan test equipment realized by this method is bulky, inconvenient to carry and manipulate, high in cost, and inconvenient to upgrade. Contents of the invention [0003] The technical problem ...
