Abstract
In modern warfare, unpowered glide munitions, represented by JDAM, are widely used. Accurately predicting the future trajectory of such targets is crucial for intercepting them. This paper proposes a future point prediction method for unpowered gliding targets based on attitude computation. By estimating the current state of the target, we derive the target’s attitude coordinate system. Subsequently, the paper analyzes the forces acting on the target and updates the state transition matrix, ultimately calculating the future position of the target. Experimental results show that, compared to traditional methods, this approach improves the accuracy of future point predictions by 9% to 45%.
