The invention discloses an unmanned aerial vehicle ISAC channel estimation method under a beam jitter effect. The method comprises the following steps: step 1, acquiring a measured value of a state of an unmanned aerial vehicle at a tth moment by adopting an inertial navigation system INS; step 2, predicting and estimating the measured value of the state of the unmanned aerial vehicle at the t-th moment by using an unscented Kalman filtering algorithm by using a computer to obtain a state estimated value of the state of the unmanned aerial vehicle at the t-th moment; and step 3, inputting a state estimation value of the state of the unmanned aerial vehicle at the tth moment by adopting a computer, and establishing a channel model with a jitter effect between the pth antenna of the unmanned aerial vehicle and the qth antenna of the ground terminal. The method is simple in step, the estimation value of the unmanned aerial vehicle is obtained through the unscented Kalman filtering algorithm, and therefore the un
