Abstract： Aiming at the inaccuracy location information of eavesdroppers in the secure communication scenario of UAV and the problem of NFZ in UAV flight， the secure transmission of UAV communication network assisted by IRS is studied. An optimization problem is constructed to maximize the Average Secrecy Rate in the worst case. The alternating optimization algorithm， phase alignment and successive convex approximation method are used to jointly optimize the IRS phase shift， UAV flight trajectory and UAV transmission power. The simulation results show that the proposed scheme can address the problem of imperfect location information of eavesdroppers and NFZ， and improve the Average Secrecy Rate in the worst case.
