31 * \brief This block estimates the range with peaks given from a FSK spectrum. Needed
32 * identifiers (symbols) are 'frequency' and 'phase'. The velocity is calculated with the
33 * 'frequency' information and the doppler formula. The phase of the doppler peaks are
34 * used to estimate the range. Output identifier are 'range' and 'velocity'. If push_power
35 * is true the information about the power of the peaks is pushed through. This can be
36 * used for estimating the RCS of an object.
37 *
38 * \param center_freq Center frequency
39 * \param delta_freq Frequency difference of high and low frequency
40 * \param push_power Toggle pushing through information about power of peaks
