Integrated sensing and communications (ISAC) is a key technique for UAV communications. In this letter, we consider the ISAC design for UAV aided communications. Firstly, we build the spatial model under the jittering effects. Meanwhile, we analyze the effect of the UAV movement and attitude variation to the channel. Then, we propose an efficient channel estimation method by utilizing the ISAC technique, where the UAV sensing, the communications, and the control are jointly considered to benefit the system performance. Finally, we provide various simulation results to verify the performance of the proposed method.
