Guidance - Based Missile Allocation Algorithm Against a Salvo Attack

The common SHOOT- LOOK- SHOOT doctrine is usually very efficient in defending strategic or tactical targets from a salvo attack. Nevertheless, using this doctrine is not always practical due to time constraints. This paper proposes an algorithm which is based on the SHOOT- SHOOT- LOOK doctrine. Solutions to two main problems that arise while applying this algorithm are presented: finding the locations of the defending missiles for the second SHOOT stage, and deriving the optimal allocation plan of the defending missiles to the attacking missiles. Probabilistic analysis was done based on the expected miss distance that was calculated from the guidance law and geometry of the problem. The proposed analysis will allow in the future further insight regarding the relationship between the guidance laws used by the designer of the air defense system, and the targets' survival probability. The results show that using the algorithm dramatically increases the probability that the defended targets will survive the salvo attack, in comparison to using a doctrine of a single SHOOT stage with an identical number of defending missiles.
