Abstract

Unmanned aerial vehicles (UAVs) deployed as a swarm can offer a flexible and cost-efficient solution for surveillance missions in large-scale adversarial environments. UAV swarms possess superior real-time surveillance capabilities in detecting time-sensitive targets with speed and security, surpassing alternative techniques such as satellites and ground-based sensors. However, the area surveillance problem in adversarial scenarios using UAV swarms necessitates careful consideration of factors such as swarm positioning, flight attitudes, antenna directionality, the threat posed by adversary detection systems (ADSs), and swarm network topology. To address this challenge, we propose the Integrated Low Detection Probability (ILDP) deployment method for UAV swarms, which incorporates the Danger Avoidance Distributed Motion control algorithm (DADM) for swarm collaboration and the Low Detection Probability Topology Control algorithm (LDPTC) for swarm networking. The DADM algorithm facilitates swarm cooperation in achieving area coverage and evading ADSs by leveraging neighboring, environmental, and threat information in adversarial scenarios. Furthermore, the LDPTC algorithm establishes a topology optimization model that comprehensively considers swarm distribution and the impact of directional antenna sidelobes to reduce transmitting energy leakage on the ground. Our strategy significantly decreases the detection probability of UAV swarms by ADSs, ensuring the operational effectiveness of UAV swarms in dynamic adversarial scenarios. Extensive simulations validate the superiority of our proposed ILDP method, demonstrating considerably lower detection probabilities compared to other approaches in static and dynamic adversary environments across various swarm scales. Moreover, our method excels in real-time surveillance capabilities with lower computational complexity, freeing up computing resources for UAVs to fulfill additional tasks.
