For the self-destroyed scout-attack integrated UAVs guided by TV or IR image,according to the definition of hit accuracy denoted by CEP under the normal distribution assumption for the landing deviation relative to target,the mathematic relationship of CEP with the system landing deviation and standard deviation is derived,while ignoring the rotation effects of UAVs.Furthermore,combined with the system operating principle and the dive attack process,mathematical equations are established to relate the CEP to the angular system errors and random errors of tracking and guiding based on the video imaging and the blind guiding distance (that is the shortest effective guiding distance to target).Examples of calculation and analysis are then given using the Mathcard software.This method can determine the tracking and guiding angular errors for given CEP and blind guiding distance,and predict whether or not the required CEP can be realized for certain tracking and guiding angular errors and blind guiding distance.
