/*! Generates a signal for FMCW radar in baseband.
31
*
32
* The generated signal consists of three parts, in this order:
33
*
34
* 1. CW part with constant frequency
35
* 2. Up-chirp
36
* 3. Down-chirp
37
*
38
* The up-chirp goes from CW frequency to CW frequency plus sweep frequency
39
* and the down-chirp goes in the opposite direction. All of these parts
40
* can be disabled by setting the corresponding length to zero.
41
*
42
* The packet length for subsequent tagged streams is calculated by the sum
43
* of the number of samples of the single modulations parts.
