Abstract
The present invention provides a radar velocity measurement system, method, and radar device. The system includes a radar module and an electrically connected signal processor. The radar module includes a transmission antenna and a receive antenna. The signal processor includes a sequence unit, a conversion unit, and a compare calculation unit that are coupled with each other. The sequence unit establishes an even number receive sequence and an odd number receive sequence. The conversion unit carries out a time domain to frequency domain conversion upon the receive sequences to generate a first reflection signal and a second reflection signal, respectively. The compare calculation unit uses an interpolation method to compare the phase difference between the reflection signals with a comparison model to obtain a true velocity. Therefore, the present invention effectively prevents the velocity ambiguity issue of radar system.
