Abstract

The invention relates to a calibrating method for signal detection equipment based on a time-frequency parameter standard instrument. The calibrating method for signal detection equipment provided by the invention comprises the following steps: remotely controlling an external radiation signal source, a standard test instrument and to-be-detected signal detection equipment; collecting output information such as time-frequency parameters of the external radiation signal source; comparatively analyzing standard data detected by the standard test instrument and the output data of the to-be-detected equipment to give the accuracy class and operating recommendation of the to-be-detected equipment. The calibrating method for signal detection equipment, provided by the invention, can repeatedly use a test plan, and particularly when parameter settings on aspects such as equipment, instruments, signal sources, data acquisition, results and the like are involved, the reused plan can save workload well. Moreover, the plan and field test can be separated. The plan is formulated before field test, so that the field test time is shortened and the using convenience of the calibrating method is improved.

Description

technical field [0001] The invention relates to the field of equipment calibration, in particular to a signal detection equipment calibration method based on a time-frequency parameter standard instrument mode. Background technique [0002] The accuracy of the measurement data of the signal monitoring equipment directly affects the quality of the product. In order to ensure the accuracy and reliability of the equipment, it must be calibrated when the model is developed and delivered to the user. The existing signal calibration methods include time-frequency parameter calibration and airspace parameter calibration of the signal. However, there are many problems in the existing technology in terms of time-domain parameter calibration and airspace parameter calibration. The process is complicated, the operation time is long, the operator is prone to fatigue and make mistakes, etc., so a new calibration method is required to calibrate the signal detection equipment.
