Fire Effectiveness Assessment for Terminal Correction Cluster Warhead Attacking Area Target

The importance of the function structure of area target is ignored by Circular Error Probability (CEP) and hit probability,which are the usual indexes for evaluating the fire precision.However,hitting the area with different importance means the difference of fire effectiveness.The fire effectiveness assessment for terminal correction cluster warhead attacking area target was focused on,based on simulating the impact point of the sub-munitions,and dividing the function area of the target by the method of damage tree,the hit probability of sub-munitions to each sub-area,which is Pi,was computed by Monte-Carlo.After that,the hit degree and the damage probability based on the importance of sub-area were defined to assess the fire effectiveness.An example shows the method is reasonable,and by uniform design,the effect of some of the technical parameters of cluster warhead to fire effectiveness is analyzed.
