Anti-warning-based anti-interception avoiding penetration strategy in midcourse

An anti-warning-based anti-interception avoiding penetration strategy is proposed for fully exploiting potential of the multi-pulse maneuvering and improving the midcourse penetration ability of ballistic missiles. With the interception system being regarded as threats and transformed into the constraint conditions, the multi-pulse trajectory design is turned into an obstacle avoidance path planning for the unmanned aerial vehicle, wherein the pulse ignition point and interval are regarded as the search nodes and step, respectively. The optimal ignition parameters are selected based on a comprehensive consideration of the detection system delay and the performance and deployment of the interception system. Influence of pulse increment and system delay on multi-pulse trajectory is studied Simulation results show that the proposed strategy can damage the convergence of enemy's prediction algorithm by multi-pulse maneuvering, and the accuracy of hostile warning results is thus reduced. When the enemy's prediction error sufficiently converges and the hostile warning is accurate enough, the missile is already being out of the range of interception. According to the latest information in battlefield, an optimal multi-pulse trajectory can be designed offline in 60 s, which can increase (decrease) the flight altitude and the average flight speed, and shorten (prolong) the flight time by 20%-35%.
