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'.
