To provide an unmanned aircraft, search device, search method, program and search system which quickly find out a lost movable body.SOLUTION: A search system 100 comprises: a search area setting unit 11 which sets a search area on the basis of a lost position where a lost movable body 30 was lost and movement state information of the movable body 30 before being lost; a node setting unit 12 which sets a plurality of nodes according to an area of the search area; an expectation level calculation unit 13 which calculates an initial expectation level set for each node on the basis of the lost position and the movement direction of the movable body 30 before being lost prior to the flight; an adjustment unit 15 which adjusts the expectation level set for each node on the basis of the radio field intensity of the radio wave received by an unmanned aircraft 20 for search, and the position and the altitude of reception of the radio wave; and a flight route generation unit 14 which generates a flight route by using the node selected on the basis of the expectation level.SELECTED DRAWING: Figure 1

    【課題】遺失した移動体を迅速に捜し出す、無人航空機、捜索装置、捜索方法、プログラム、及び捜索システムを提供する。【解決手段】捜索システム100は、遺失した移動体30を遺失した遺失位置と、遺失前の移動体30の移動状態情報とに基づいて捜索エリアを設定する、捜索エリア設定部11と、捜索エリアの面積に応じて複数のノードを設定する、ノード設定部12と、飛行前において、遺失位置と、遺失前の移動体30の移動方向とに基づいて、ノードそれぞれに設定する初期期待度を算出する、期待度算出部13と、ノードそれぞれに設定された期待度を、捜索用の無人航空機20が受信した電波の電波強度と、電波を受信した位置及び高度とに基づいて調整する、調整部15と、期待度に基づいて選択したノードを用いて飛行ルートを生成する、飛行ルート生成部14と、を有する。【選択図】図1
