Problems solved by technology

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
[0004] The traditional positioning calculation method considers that the error elements of each target receiving station are correlated when calculating the positioning accuracy, which reduces the efficiency of the positioning accuracy calculation and increases the complexity of the positioning accuracy calculation. Therefore, it is urgent to propose A New Calculation Method of Positioning Accuracy

Abstract

The invention belongs to the technical filed of real-time positioning of a distributed multi-point positioning monitoring system and particularly relates to a positioning accuracy resolving method for a distributed multi-point positioning monitoring system. The positioning accuracy resolving method includes determining the position information of the receiving station master station of a target, differentiating the position information of the area to be positioned, solving the correlation coefficient matrix of the target and the receiving station master station position of the target and the target and the receiving station slave station position, calculating the error estimation value of the area to be positioned by means of the pseudo inverse method, and finally obtaining the positioning accuracy of the area to be positioned. The set measured error is zero-mean after being corrected by the system, the target receiving station error elements and the station address errors are not related, so that the complexity of the positioning accuracy resolving method is greatly reduced and the efficiency of positioning accuracy resolution is improved.

Description

technical field [0001] The invention belongs to the technical field of real-time positioning of a distributed multi-point positioning monitoring system, and in particular relates to a positioning accuracy calculation method for a distributed multi-point 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 a...
