Abstract

The invention discloses a pairing method used for a distributed multi-point positioning and monitoring system. The method is used for pairing response signals and is also used for pairing calibration signals. Subsequently, error compensation of a system is obtained according to a calibration station measurement position which is calculated according to the paired calibration signals and an actual position of the calibration station. And then, the error compensation of the system is used to carry out error compensation the measurement position of a target so as to achieve accurate target positioning. By using the pairing method of the invention, data quality control processing is performed on the signals, and then consistency matching processing is performed on the signal after the data quality control processing. Through the method of the invention, pairing accuracy of a response signal and a calibration signal is increased, positioning accuracy of the response signal and the calibration signal is improved, and a risk that local convergence is generated because of incorrect pairing or divergence can not be correctly solved is reduced, and a reliable data basis is provided for real-time accurate positioning of the target and the calibration station.

Description

technical field [0001] The invention relates to the technical field of distributed multipoint positioning monitoring, in particular to a pairing method for a distributed multipoint positioning monitoring system. Background technique [0002] With the rapid development of my country's economy, the number of flights is also increasing rapidly, which puts forward higher requirements for the command of the air traffic control system controller and the maintenance of facilities and equipment. The airport surface surveillance radar is a radar, mainly used to monitor the airport scene Aircraft and vehicles use the target's own radiation or reflection characteristics of electromagnetic waves to find targets. In the process of maintaining the airport surface surveillance radar, equipment maintenance personnel include the following three problems: aircraft target splitting, certain blind spots, and false targets are prone to appear. The existence of these problems disrupts the normal ...
