Calibration method of signal detection equipment based on airspace parameter standard signal source

Abstract

The invention relates to a signal detection equipment calibrating method based on an airspace parameter standard signal source manner. According to the signal detection equipment calibrating method disclosed by the invention, a standard antenna and signal detection equipment to be detected can be remotely controlled, the GPS (Global Positioning System) longitude and latitude data and north positioning errors of the standard antenna and the GPS data of the equipment to be detected are collected to obtain the reference value of an azimuth angle, and comparative analysis is carried out on the measured value of the azimuth angle detected by the equipment to be detected and the reference value of the azimuth angle, so that the accuracy grade and operation suggestions of the equipment to be detected are given out. The signal detection equipment calibrating method disclosed by the invention can reuse a test plan, and particularly during the parameter setting in the aspects of equipment, instruments, signal sources, data collection, results and the like, the workload can be greatly saved through the reusing of the plan; meanwhile, the plan can be separated with a site test, the plan is prepared before the site test, and thus the site test time is reduced, 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 method for calibrating signal detection equipment based on a standard signal source of airspace parameters. 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.
