%X The purpose of this paper is calculating the detection probability of an aircraft traveling near an opponent multi-radar system.Based on the aircraft RCS(Radar Cross Section) model,flight route,radar character parameter and locations,detection times of sub-radars and detection state parameters are calculated.Further more;the instantaneous detection probabilities of each radar are given.Then,the accumulated detection probability is calculated.At last,multi-radar system detection probability is obtained.The method here takes into account the aircraft RCS changing with the different detection attitude;this is more precise than the method which considers the RCS as constant.The accumulated detection probability is used to replace the traditional instantaneous detection probability;so the result get here is the probability of the whole flight process.Taking multi-radar as a detection system is more suitable for the further development of radar.The numerical result shows that the method is effective and feasible.
