Airship monitoring is a technology that uses airships to carry photoelectric equipment to continuously observe targets. Limited by equipment performance and aircraft altitude, the monitoring system has a limited observation area and cannot cover all target points in the area. In order to efficiently display the benefits of equipment and cover as many targets as possible, it is necessary to reasonably plan the location of the monitoring system. By modeling the problem of the maximum coverage of airship monitoring, the article uses the search algorithm based on mesh division, the search algorithm to determine the center of the circle, the search algorithm to determine the arc, and the most value solution algorithm of the function. Through simulation analysis, the results of the above algorithm are carried out to compare.
