Collaborative multi-platform network for underwater detection in the future have advantages like comprehensive data acquisition, highly parallel operation, better concealment, stronger antiinterference ability, more flexible configuration. The performance of multi-platform underwater network is determined by the characteristic of acoustic propagation environment, collaboration ability between sensors and the cost of the system. In order to exploit the advantages of the system and maximize the use of existing platforms, this paper studied the underwater detection performance considering the interference between each other in the energy constrained underwater acoustic channels. We summarized the relationship between the underwater detection performance and the platform number, position of platform, operating parameters, interference suppression capabilities, target heading parameters. Provide a theoretical basis for the formation of multi-platform network under the performance requirements.
