Embodiment 1
[0096] Numerical simulation proves that the system and method of the present invention can overcome the influence of hostile aircraft maliciously blocking the cluster and stealing the position of our base under the directed communication network.
[0097] Consider a network system composed of three aircraft (numbered 1, 2, 4) of our side under a directed communication network, and its communication topology is as follows Figure 5 (a) shown. Under this directed communication network, three aircraft of our side hope to realize the central cluster. At this time, the aircraft of the enemy (aircraft 3) appears in our field of vision, disguises as our aircraft, and exchanges information with our aircraft. formed as Figure 5 (b) Shown in the directed topological network, the enemy aircraft tries to block the swarm of our aircraft and steal the location of our base. At this time, it is proved that adopting the technical solution of the present invention can resist the interference...

The invention discloses a multi-aircraft cluster privacy protection system and method under a directed communication network, and the system comprises a first determination module which determines an improved Laplacian matrix of a multi-aircraft network at the current moment, a second determination module which determines an update parameter, a third determination module which determines an interference signal added for privacy protection, and a third determination module which determines an interference signal added for privacy protection. The acquisition module acquires the position of each individual aircraft at the current moment and the position information of the added interference signal transmitted by the incoming neighbor aircraft of each individual aircraft at the current moment, and the control module controls each individual aircraft according to the information acquired by the above modules. By means of the technical scheme, it can be guaranteed that under the condition that directed communication networks exist between the aircrafts, when malicious enemy aircrafts are mixed into our aircraft networks, our aircraft clusters are not hindered, and the initial positions of the our aircrafts are not exposed.
Description
technical field [0001] The invention belongs to the technical field of aircraft control, and in particular relates to a central cluster privacy protection system and method for multiple aircraft under a directed communication network. Background technique [0002] At present, aircraft swarm coordination has gained widespread attention in practical applications. As a brand-new mission execution form, it is gradually becoming an effective way to generate system combat capabilities. It is increasingly difficult for a single aircraft to perform reconnaissance and attack missions alone due to the limitations of observation angle, combat range, strike accuracy, and killing radius. Clusters can be realized through directed information exchange between multiple aircrafts. When a local failure occurs in the multi-aircraft network, scheduled tasks can still be completed through information exchange. [0003] In practical applications, the multi-aircraft network may be interfered by e...
