An Analysis Method for Hit Accuracy of Gun-Launched Reconnaissance and Strike Integrated Unmanned Aerial Vehicle

An analysis method for the hit accuracy of a gun-launched unmanned reconnaissance and strike integrated Unmanned Aerial Vehicle (UAV), guided by a half-strap down seeker, is proposed, while the sensitivity in the guidance blind range is analyzed. First, based on the analysis of UAV motion feature, the calculation of circular error and hit probability values are derived, using trapezoidal double integral method; then, the guidance model, the control model and the steering gear model, based on the constraint of falling angle, are constructed. The Monte Carlo shooting of UAV is used to attack stationary and moving targets at different blind zones of guidance values, while the sensitivity of target circular error probability and collision probability of the UAV is analyzed. The simulation results indicate that, the circular error probability of UAV increases rapidly, while the collision probability decreases rapidly, as the value rises, whereas at values, the hit accuracy decreases more rapidly. This proposed approach can lay a foundation for the analysis of system indicators in reconnaissance and strike integrated UAVs.
