Detailed Description

Generates a signal for FMCW radar in baseband.

The generated signal consists of three parts, in this order:

1. CW part with constant frequency
2. Up-chirp
3. Down-chirp

The up-chirp goes from CW frequency to CW frequency plus sweep frequency and the down-chirp goes in the opposite direction. All of these parts can be disabled by setting the corresponding length to zero.

The packet length for subsequent tagged streams is calculated by the sum of the number of samples of the single modulations parts.
