31  * \brief This block estimates range and veloicty from peaks of a FMCW spectrum. Input
32  * messages are data with the identifier 'frequency' of the up-chirp, down-chirp and CW
33  * part. If data is available on all three message ports the estimation starts. The
34  * velocity is estimated with the frequency information of the CW block and the range is
35  * estimated with the up and down chirp. If multiple frequencies are given, the velocity
36  * is estimated first and associated with the most likely range from the up- and
37  * down-chirp. The output identifiers are 'range' and 'velocity'.
