Source code of the Signal Generatoe FMCW Out of the tree block.

That block is part of the gr-radar OOT module, and the source code is on GitHub at https://github.com/kit-cel/gr-radar/blob/master/lib/signal_generator_fmcw_c_impl.cc. It's not a Python block, but C++. The GRC YAML file is here https://github.com/kit-cel/gr-radar/blob/master/grc/radar_signal_generator_fmcw_c.block.yml.

Can you share a example imolementation of this block because some parameters of the block are confusing to me. Or a detailed explanation of the required input parameters?

[ryanvolz]

Sorry, I didn't write the block not have I ever used it, so I don't know anything more than what I've already linked. Looking at the code, it appears that the block outputs 3 blocks of samples of specified lengths before repeating:

1. Samples CW samples of CW at the specified Frequency CW
2. Samples up-chirp samples of of the signal linearly increasing in frequency starting at Frequency CW and ending at Frequency CW + Sweep frequency
3. Samples down-chirp samples of of the signal linearly decreasing in frequency starting at Frequency CW + Sweep frequency and ending at Frequency CW

okay thank you very much
