Deployment Planning Algorithm of Unmanned Underwater Swarm Based on Probability Model of Single-platform Detection

In marine environment monitoring, offshore exploration, military tactical reconnaissance and other missions, the detection performance of unmanned underwater swarm depends on the deployment planning of swarm and the detection performance model of single platform. In this paper, a probability model of single platform for area detection is proposed based on the active sonar process and the navy interim surface ship model(NISSM) sonar model. An unmanned platform deployment planning algorithm in a specified area using a Gaussian mutation operator and a tournament selection mechanism is proposed based on cuckoo search algorithm. Simulation result indicates that the probability model of single-platform detection can give detection probability of each point in a region quantitatively, and can effectively reflect the uncertainty of detection information, which is induced by the restriction of platform’s parameter and marine environment. And the attenuation of the platform detection capability relates to the false alarm probability. The proposed algorithm performs better than the cuckoo search algorithm in terms of higher slope of the evolution curve, and faster convergence speed. For different number of platforms, the effective detection coverage rate of the unmanned platform deployment planning algorithm is more than 0.8, 0.2 higher than that of the random deployment.
