Information processing device and non-transitory computer-readable storage medium storing program

An information processing device comprising:

• a communication device configured to receive information including a first height and a first strength indicating a strength of a radio signal related to position information and received at a position of the first height;
• a second determination device configured to determine that the first height is a water level when an attenuation amount of the first strength with respect to a reference strength exceeds a predetermined value;
• an acquisition device that acquires, as a second strength, a strength of the radio signal received at a position of a second height different from the first height;
• and
• an first determination device that determines that the second height is a water level when an attenuation amount of the second strength with respect to the reference strength exceeds the predetermined value, wherein
• the acquisition device includes:
• one antenna configured to receive the radio signal;
• a first moving device configured to move the antenna from the position of the first height to the position of the second height;
• and
• a receiving device configured to calculate a strength of the radio signal received by the antenna at the first height as the first strength and calculate a strength of the radio signal received by the antenna at the second height as the second strength, and
• the first moving device moves the antenna from the position of the first height to the position of the second height when the first determination device determines that the attenuation amount of the first strength exceeds the predetermined value while the antenna is disposed at the position of the first height.

A non-transitory computer-readable storage medium storing a program, the program being configured to cause a computer to execute:
