Embodiment Construction

[0043] Exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be understood that the implementations shown and described in the drawings are only exemplary, intended to explain the principle and spirit of the present invention, rather than limit the scope of the present invention.

[0044] The embodiment of the present invention provides a cooperative search method for UAV targets with discontinuous observation characteristics, such as figure 1 As shown, the following steps S1-S14 are included:

[0045] S1. Establish a search environment model according to the search target activity area.

[0046] In the embodiment of the present invention, the influence of factors such as terrain is not considered, the ground target can move in the target area, and the unmanned aerial vehicle can fly over the target area, and the search environment model finally established is as follows: figure 2 shown. figur...

Abstract

The invention discloses an unmanned aerial vehicle cooperative search method for targets with non-continuous observation characteristics. In view of the application demand that the observation characteristics of the targets change with time in a real application scene and have no continuous observation characteristics, the invention provides a dynamic sliding variable window update target search payoff diagram method, in which a distributed cooperative path search optimization mechanism is adopted, and the constraint of unmanned aerial vehicle link connectivity is added to a search performancefunction calculation, so that the inaccuracy of judging the non-continuous observation targets by the traditional search method is solved, the target search efficiency is improved, and the time required for target search is shortened.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicle search, and in particular relates to the design of an unmanned aerial vehicle cooperative search method for targets with discontinuous observation characteristics. Background technique [0002] With the development and maturity of UAV (Unmanned Aerial Vehicle, UAV) technology, it has been increasingly applied to target search tasks in recent years and has become an important aerial search platform. When a single UAV performs reconnaissance and search tasks, it faces limitations such as battery life, search range, and sensor accuracy, and its application fields are restricted. Multiple UAVs cooperate to search the area, which can search the mission area more comprehensively and thoroughly, better find the target and obtain intelligence information, and make new changes in the target search method. [0003] The problem of UAV-based target search has always been a hot topic of resear...
