摘要

PROBLEM TO BE SOLVED: To provide a searching system and a device at sea, by which searching can be definitely performed according to a search object and a search region, and to provide a program for executing the search.

SOLUTION: The searching method of searching for the object floating, drifting or traveling at sea comprises: an input device 103 for inputting a hydrographic phenomenon condition of the sea area of the floating, drifting or traveling object; a reading device 101 for reading variation in detection rate according to the input hydrographic phenomenon condition and the size of the object from a database 106 beforehand stored in a storage device 105; a calculating device 102 for calculating the recognition probability of the object based on the read variation in detection rate; and an output device 104 for outputting search mode calculated by the calculating device. A search condition is determined based on the hydrographic phenomenon condition.
