The effectiveness of exoatmospheric interceptor is analyzed in this paper based on the reachable set model. Firstly, the connotations of the reachable set model, including its precise definition, mathematic description and analysis algorithms are briefly introduced. Secondly, concerning the problem of interceptor system deployment, the defense zone is introduced as a metric of effectiveness. The factors that influence the configurations of defense zone are explored. Thirdly, concerning the problem of incoming target assignment, an index system composed of earliest intercept moment, interception time window and radar support distance is drawn to capture the effectiveness. The selection of optimal intercept plan is treated as a multi-alternatives sequencing problem and addressed by the multiple attribute decision making method. Simulation examples prove the efficiency of the raised approach. The reachable set-based approach proposed in this paper serves as a ready support to other studies related to interceptor capability.
