The invention also discloses a flight vehicle anti-collision algorithm verification testing system.

Description

technical field [0001] The invention relates to the technical field of aviation flight, in particular to a verification test method and system for an aircraft collision avoidance algorithm. Background technique [0002] Anti-collision avoidance is a safety measure that must be taken after an aircraft detects a flight conflict during flight. The efficiency of the anti-collision algorithm directly affects the flight safety of the aircraft and the intruder aircraft. According to whether the intruder aircraft in the airspace has communication interaction and flight plan sharing with the local aircraft, the intruder aircraft are divided into two categories: cooperative targets and non-cooperative targets. The cooperative intruder aircraft is equipped with an onboard anti-collision system and can communicate with the local aircraft. Shared with the flight plan, non-cooperative intruder aircraft are generally not equipped with airborne collision avoidance systems and cannot communi...

Problems solved by technology

The test conclusion obtained by the former method is the most authentic and reliable test data, but the cost of the test is high, the risk is high, and the efficiency is low

The latter test method is simple to implement and low in cost, but it can only output simple theoretical data curves, which lacks intuition, and the algorithm simulation often ignores the maneuverability parameters and environmental parameters of the aircraft itself. The final simulation results of collision avoidance ability can be low reliability
