Claim:
1. A speed measuring device for a moving body, comprising: an antenna having directionality that transmits a transmission wave toward the moving body based on a supplied transmission signal and generates a reception signal by receiving a reflected wave reflected by the moving body, the moving body including a first moving body and a second moving body launched by being struck by the first moving body; a Doppler sensor that supplies the transmission signal to the antenna and generates a Doppler signal having a Doppler frequency based on the reception signal; a measurement processing unit that calculates a movement speed of the moving body based on the Doppler signal, the measurement processing unit comprising: a display that displays display content including the calculated movement speed, displays the first speed data as a first movement speed of when the first moving object strikes the second moving object, and displays the second speed data as a second movement speed of when the second moving body is launched; a housing that holds at least the display; and an antenna supporting unit provided on the housing that supports the antenna so that an inclination of an imaginary axis can be altered when an imaginary line extending along a direction where a gain of the antenna is maximized is defined as the imaginary axis that indicates an orientation direction of the antenna.
