Recommended sensor placement devices, recommended sensor placement methods, and recommended sensor placement programs

Abstract

To provide a sensor arrangement recommendation device with which it is possible to recommend efficient arrangement positions of a plurality of sensors when searching for a target.SOLUTION: A sensor arrangement recommendation device 20 comprises: a prediction unit 21 that predicts, for an object which moves in an underwater search area and which is the target searched by a sensor of a search system, a target presence zone in the search area where the target is present after elapse of a prescribed time; a first determination unit 22 that determines a sensor arrangement position at which a probability of searching for the target is highest, using the predicted target presence zone, after the elapse of the prescribed time; and a second determination unit 23 that determines to locate a new sensor in an area at which the arranged sensor does not satisfy a prescribed condition for searching for the target in the predicted target presence zone, when the sensor is located at the determined arrangement position.SELECTED DRAWING: Figure 11
