In this paper, a 4D trajectory planning problem of a multiple unmanned combat aerial vehicle (multi-UCAV) cooperative formation based on given 4D navigation points is studied. The three degrees of freedom model of the unmanned combat aerial vehicle (UCAV) will be established first. Then, the development of current tau theory is introduced and an improved tau-j guidance strategy is proposed. The improved tau-j guidance strategy addresses the discontinuity of velocity and acceleration at the navigation point in the original tau-j theory. The speed and acceleration of the generated four-dimensional trajectory are controlled to meet the flight requirements of the UCAV. Finally, a cost function considering the length of the flight path, flight time, collision avoidance, maximum acceleration, minimum and maximum speed of UCAV is proposed. The Particle Swarm Optimization (PSO) algorithm is used to optimize the four-dimensional trajectory of the UCAV. The results of the mathematical simulation show that the four-dimensional trajectory planning algorithm of the multi-UCAV cooperative formation meets the requirements of the constraints, which proves the effectiveness of the trajectory planning algorithm.
