To reduce the false alarms and improving the accuracy of collision warning,the application of expert system in intelligent collision warning was developed.The alerting area and evading area were built according to the collision warning decision mechanism.And the threshold value was used by the collision warning expert system to make the decision to evasive maneuver or not.The expert system was designed using forward inference rules and Rete pattern-matching algorithm,then developed in the C Language Integrated Production System(CLIPS) compilation environment,and simulated.The results of the simulation show that the collision warning expert system makes accurate action output according the input of relative position information of two objects.It achieves the purpose of spacecraft collision warning.
