MEASUREMENT DEVICE, MEASUREMENT METHOD, AND COMPUTER-READABLE MEDIUM
A measurement device includes a memory; and a hardware processor coupled to the memory. The hardware processor is configured to: detect a vibration width of an antenna that receives a measurement target radio wave from a target on which a communication system that transmits the measurement target radio wave is mounted, based on a first reception radio wave received by the antenna; and derive communication performance of the communication system, based on a second reception radio wave that is the measurement target radio wave received by the antenna when the vibration width is greater than 0 and equal to or smaller than a set width greater than 0.
