Joint power and time allocation algorithm in multi-radar system for cooperative target detection
In this study,a joint power and time allocation algorithm in multi-radar system for cooperative target detection is proposed in multi-target search and tracking scenarios.The evaluation metrics for radar search and tracking performance are derived separately,based on signal detection theory and the Cramér-Rao lower bound.A joint optimization allocation model is developed for multi-aircraft radar systems geared towards cooperative detection.This model seeks to maximize radar opera-tional performance as the optimization objective,which will be achieved under the constraint of predefined system resource.Parameters including radar selection,radiated power,and time in radar search and tracking missions are jointly optimized.By incorporating the interior point method and particle swarm algorithm,a three-step decomposition approach is employed to solving the optimization problem.The results reveal that the proposed algorithm compared to existing algorithms improves ra-dar system search performance and tracking accuracy effectively while adhering to the predefined system resource constraint.
