The invention relates to the technical field of monitoring of civil aviation aircrafts, and particularly discloses an evaluation method for availability of required monitoring performance. The methodcomprises the steps of receiving monitoring data of each track; establishing reference tracks in a one-to-one correspondence manner according to the received monitoring data; dividing the reference tracks according to measurement interval time and calculating the number NT of measurement intervals of each reference track; calculating the number NR of measurement intervals with effective horizontalpositions in each reference track and calculating the horizontal position update rates PUR of all the reference tracks; calculating the number NH of measurement intervals with effective air pressureheight existing in each reference track and calculating the horizontal position updating rate PUH of all the reference tracks; calculating the number NI of measurement intervals with effective aircraft identities existing in each reference flight path and calculating aircraft identity update rates PUI of all the reference flight paths; and calculating the availability of the monitoring performancerequired by a monitoring system according to the horizontal position update rate PUR, the air pressure altitude update rate PUH and the airplane identity update rate PUI.
Description
Technical field [0001] The invention relates to the technical field of civil aviation aircraft monitoring, in particular to a method for evaluating the availability of required monitoring performance. Background technique [0002] Aviation surveillance (Surveillance) technology is an important part of the International Civil Aviation Organization's new navigation system (CNS / ATM). It is a combination of satellite-based positioning and navigation, aircraft airborne equipment and ground equipment and other advanced technologies. Providing necessary aviation operational situation awareness information is the foundation of modern air traffic management and an important means to ensure flight safety and improve operational efficiency. The air traffic control automation system, as the core system for the civil aviation control department to implement air command, provides the controller with the display of the air flight situation and various flights by processing surveillance radar si...
