The invention provides a verification method and device, which relate to the technical field of traveling wave ranging device verification. The method includes the following steps: acquiring standarddata, and generating a first analog signal according to the standard data; if a trigger signal is received, triggering a first traveling wave ranging device to send the first analog signal to a secondtraveling wave ranging device, and recording the current time as a first time; receiving a second time returned by the first traveling wave ranging device, wherein the second time is the time when the first traveling wave ranging device receives a second analog signal sent by the second traveling wave ranging device, and the second analog signal is generated under the triggering of the trigger signal; obtaining test data according to the first time and the second time; and generating a judgment result according to the test data and the standard data. The purpose of verifying the second traveling wave ranging device is
