求解弹头散布均匀度的分布估计算法

The future-air-window is a new shooting system of anti-aircraft gun. This shooting system has distinct effect on short-range antiaircraft and antimissile. Since the cannonball dispersion evenness(CDE) is required to be computed when designing the future airspace window(FAW), and the computing algorithm should be globally convergent and with high solution accuracy, a hybrid algorithm to meet these requirements is proposed in this paper. First, the problem of solving FAW cannonball dispersion evenness is described; second, an algorithm for estimating the cannonball dispersion evenness(CDE) is put forward; and then, a zooming algorithm is employed to improve the search efficiency and solution accuracy, and the flowchart of the hybrid algorithm is given. The simulation results verify that the proposed hybrid algorithm has the advantages of global convergence, high solution precision and high search efficiency. It is suitable for the solution of CDE in practical engineering.
