The invention relates to the aviation flight field, and discloses a flight vehicle anti-collision algorithm verification testing method. The flight vehicle anti-collision algorithm verification testing method comprises steps that step1, track data is acquired; step2, simulation scene parameters are set; step3, by adopting a cylindrical security domain establishing method, an evasion domain and a collision domain are established automatically; step 4, a track collision point is calculated, and when the anti-collision evasion conditions of the evasion domain and the collision domain are satisfied, an anti-collision algorithm is started; step5, the anti-collision evasion performance of the anti-collision algorithm is tested; step 6, anti-collision evasion decision data is acquired, and self-adapting of anti-collision evasion decision data is carried out; step7, a display way is selected for the display and the output of the anti-collision evasion decision data; step 8, the evasion track of the anti-collision evasion decision data is evaluated and calculated; step 9, the data of the above mentioned steps 1-8 is stored, and a flight process is displayed in a real-time manner. The anti-collision evasion testing process having advantages of low costs, low risks, and high efficiency is realized. The invention also discloses a flight vehicle anti-collision algorithm verification testing system.
