Maybe slightly related: some years ago when DFS became a topic and it was hard to get hands on radar pattern generators, Christian Lamparter wrote a variant of the carl9170 fw [1] which can generate radar pulses to test ath9k and other DFS radar detectors. Pulses are generated by enabling txout at defined sampling intervals. It should be doable to mimic what you are looking for by generating a _very_ long pulse.
