The application discloses a multi-agent cooperative navigation optimization method, and the optimization method takes a multi-agent deep deterministic policy gradient algorithm as a basic framework; the following mechanism is introduced in the training stage: in the multi-agent cooperative navigation training stage, a joint priority experience extraction mechanism is introduced, joint experience samples are extracted and spliced according to the time difference error priority through cross-agent synchronization indexing; an information discarding and correction compensation mechanism is introduced at the input end of the centralized Critic network, information from other agents is divided into independent information blocks, the information blocks are randomly discarded with a preset probability, and a correction factor is applied to the retained information blocks to maintain the mathematical expectation of the input data unbiased, and the input of the reduced Critic network is obtained. The application provides a multi-agent cooperative navigation optimization method which can improve the key experience utilization rate, reduce the dependence of the model on high-dimensional global input, and enhance the robustness in a communication limited environment.

This invention relates to the field of drone smoke grenade generation and control technology, and provides a drone smoke grenade deployment control method and system. The method includes: constructing calculation models for calculating the real-time coordinates of a threat, a drone, and a smoke grenade; based on the calculation models, determining the effective shielding conditions of the smoke cloud formed by the smoke grenade against a real target in the vertical and horizontal directions; based on the calculation models and the effective shielding conditions, constructing an optimal deployment model for the drone to deploy a single smoke grenade; and deploying the smoke grenade based on the optimal deployment model to form a smoke cloud that effectively shields the real target, thereby avoiding interference from the threat. According to the solution of this invention, the effective shielding determination conditions provided by this invention are easy to operate and calculate, have high timeliness, and can accurately calculate the effective shielding duration of the smoke cloud generated by the smoke grenade against the target.
