I don't recall such a scheme being used on either system I worked on. However, skimming the paper in your sibling's post it would be something done in the RF front end, which is probably why I never encountered it. The closest I got to the front end was pseudo-raw IQ from the pulses. It was also probably tied up in the anti-jamming measures, so it wouldn't get wide circulation on the programs.
- Junk_Collector 8y agoYes it's predominately a base band technique, although it has also been written about a fair bit in literature as an efficient power spreading alternative to a classic chirp. In that case, it is predominantly done to help propagation leveraging the extensive work done in communications on "noise-like" signals. In the case of Automotive radar, using it as an identifier to prevent interference is appealing because it allows each radar to use the full 6 GHz of channel bandwidth which greatly improves the performance of the radar despite the fact that there are tons of same channel independent devices operating. Each one would effectively be a jammer otherwise.
