Abstract: The effect of connectivity between air defense units on the kill probability of penetration target is researched from the aspects of communication command and control structure and firepower collaboration. An air defense unit is used as a threat unit to create a threat netting model. A interconnectivity model for the threat units, the reliability of information routing in the network and the connectivity between the threat units. An information fusion model is established for target designation probability and radar detection probability. Based on the joint detection probability of multiple threat units which infers from the principle of radar networking using the networking fire control technology for multiple intercepting and coordinate attack on the penetration target, an final threat netting model is established. Finally,the simulating result in the C++ 6.0 environment proves the validity of the threat netting model.
