This paper introduces a novel cross-modal neural network model that aims to convert long-term temporal behavior data into natural language to achieve UAV intent recognition. Our generative intent recognition model effectively utilizes the inherent redundancy present in long temporal behavior data by incorporating a sequence compression module, which enables the cross-modal generation and alignment of intents while preserving the integrity of the standard Transformer architecture. Importantly, we observe that this approach mitigates the negative impact of imbalanced database distribution by mapping intent categories onto the modality of natural language. Furthermore, we propose three comprehensive pre-training tasks specifically designed for time series data, thoroughly examining their interconnections and analyzing the impact of a hybrid pre-training framework on the accuracy of intent recognition. Our experimental results demonstrate the superiority of our proposed generative UAV intent recognition model, along with the hybrid pre-training initialization method, compared to conventional classification models. Simultaneously, the intent recognition method exhibits heightened temporal sensitivity and robust resilience, enabling it to deal with complex UAV confrontation and interference environment.

The self-organization capabilities of massive aerial swarms pose challenges to conventional methods of grouping aerial targets. These traditional approaches struggle with issues such as stability, reliability, and the recognition of deep intentions. To overcome these challenges, we propose an architecture called Unsupervised Contrastive Learning for Aerial Targets Grouping (UCL-ATG). Our approach utilizes random time periods within the scenario as training batches for contrastive learning. The UCL-ATG model consists of four key modules: feature extraction, time series generation, fine-tuning, and clustering. The feature extraction and time series generation modules form the network architecture of Contrastive Predictive Coding (CPC). Positive and negative samples are obtained using different sampling methods. To effectively collaborate with the clustering module, we design a contrastive predictive loss function specifically tailored for clustering. This enables the extraction of low-dimensional representations that capture the high-dimensional temporal characteristics of aircraft. Furthermore, we introduce a real-time fine-tuner to enhance the model's transferability to specific tasks. The inclusion of the real-time fine-tuner greatly alleviates problems associated with evolving confrontation styles and unevenly distributed datasets, as confirmed by the performance on the validation set. Extensive comparative experimental results demonstrate our model's superior training outcomes and its ability to extract improved clustering features. In wargame applications, our model no longer relies solely on static position information of the aircraft. It exhibits outstanding capabilities in historical information memory, information synthesis, and even demonstrates aptitude in identifying friend or foe and making tactical inferences.

Aiming at the space-time cooperation problem of unmanned aerial vehicle swarms attacking sea surface moving targets, a specified-time cooperative optimal control approach is proposed. The relative motion between each UAV and its neighbors is transformed into an optimal tracker with a specified end time. Different quadratic cost functions are designed for the two control objectives, which are strike formation generation and strike formation maintenance with specified time parameters, respectively. The control law is solved by Runge-Kutta method, which could drive the UAV swarms to accurately generate strike formation at the specified time realizing simultaneous strike and maintain the strike formation in the specified period realizing continuous strike. The simulation results show that the UAV swarms could generate and maintain the desired formation at the specified time and track the stationary and moving targets.

The coordination of heterogeneous Unmanned Aerial Vehicles (UAVs) for complex, multi-stage tasks presents a significant challenge in robotics and autonomous systems. Traditional linear models often fail to capture the emergent synergistic effects and dynamic nature of multi-agent collaboration. To address these limitations, this paper proposes a novel hierarchical framework based on a Mission Chain (MC) concept. We systematically define and model key elements of multi-agent collaboration, including Mission Chains (MCs), Execution Paths (EPs), Task Networks (TNs), and Solution Spaces (SSs), creating an integrated theoretical structure. Based on this framework, we formulate the problem as a Sensor–Effector–Target Assignment challenge and propose a Marginal Return-Based Heuristic Algorithm (MRBHA) for efficient dynamic task allocation. Simulations demonstrate that our proposed MRBHA achieves a substantially higher total expected mission value—outperforming standard greedy and random assignment strategies by 14% and 77%, respectively. This validates the framework’s ability to effectively capitalize on synergistic opportunities within the UAV network. The proposed system provides a robust and scalable solution for managing complex missions in dynamic environments, with potential applications in search-and-rescue, environmental monitoring, and intelligent logistics.

During aircraft operations, pilots rely on human‐machine interaction platforms to access essential information services. However, the development of a highly usable aerial assistant necessitates the incorporation of two interaction modes: active‐command and passive‐response modes, along with three input modes: voice inputs, situation inputs, and plan inputs. This research focuses on the design of an aircraft human‐machine interaction assistant (AHMIA), which serves as a multimodal data processing and application framework for human‐to‐machine interaction in a fully voice‐controlled manner. For the voice mode, a finetuned FunASR model is employed, leveraging private aeronautical datasets to enable specific aeronautical speech recognition. For the situation mode, a hierarchical situation events extraction model is proposed, facilitating the utilization of high‐level situational features. For the plan mode, a multi‐formations double‐code network plan diagram with a timeline is utilized to effectively represent plan information. Notably, to bridge the gap between human language and machine language, a hierarchical knowledge engine named process‐event‐condition‐order‐skill (PECOS) is introduced. PECOS provides three distinct products: the PECOS model, the PECOS state chart, and the PECOS knowledge description. Simulation results within the air confrontation scenario demonstrate that AHMIA enables active‐command and passive‐response interactions with pilots, thereby enhancing the overall interaction modality.
