The invention discloses a calibration device and a calibration method for a radio frequency homing-based semi-physical simulation system. The calibration device comprises a radio frequency simulation turntable angular position calibration module, a radio frequency simulation turntable angular rate calibration module and a radio frequency array target loudspeaker position calibration module, wherein the data information of the radio frequency simulation turntable angular position calibration module, the radio frequency simulation turntable angular rate calibration module and the radio frequency array target loudspeaker position calibration module are transmitted to an upper computer through a data acquisition and transmission device. According to the calibration device and the calibration method, the radio frequency homing-based semi-physical simulation system is calibrated through the calibration device with the three modules, so that the problem that the calibration is easily distorted in the prior art is solved; calibration data are independent of a calibrated system; the credibility of the calibration data is improved; the technical state of a radio frequency simulation system is really reflected; the position and the center of a loudspeaker are calibrated through the loudspeaker position calibration module; calibration equipment is high in precision, convenient to mount and calibrate and simple in structure; the calibration method is simple, the data are reliable, and the efficiency is high.

Description

technical field [0001] The invention relates to a calibration device and a calibration method for a semi-physical simulation system for radio frequency homing, and belongs to the technical field of instrument equipment calibration. Background technique [0002] The application of the radio frequency hardware-in-the-loop simulation system not only solves the problem of low accuracy of full digital simulation although it is simple and easy, but also overcomes the limitations of the flight test, which has high real-time performance and high reliability of results. , its large scale, long time, complex technology, and high cost limit the number of tests, and it is impossible to collect system performance data with sufficient number of tests. The performance and reliability of the weapon system play an irreplaceable role, so it is very important to calibrate the RF hardware-in-the-loop simulation system.

AI Technical Summary

Problems solved by technology

[0006] (1) The self-test monitoring data of the RF simulation system comes from different feedback units, and there is distortion in data collection and transmission, so there is a certain deviation between the data and the real technical state of the system, which cannot fully and truly reflect the RF hardware-in-the-loop simulation the technical status of the system;

[0007] (2) The self-test monitoring data of the radio frequency simulation system cannot calibrate the position of the whole column and the center of the array of the radio frequency array target simulation system
