Hello CedronI've now tested different approachs including digital mixing, autocorrelation and simple time domain phase measurements but at the end I see the same...
Hello SlartibartfastAs mentioned above, I believe we have some issues to resolve in our measurement system before we can work on the accuracy itself.We are using...
Hello CedronI appreciate your enthusiasm to support newbies like me and also what you have implemented in your blog articles.We now have a lot of input and need...
We usually work with a DFT but started some research with the CZT where we saw then the problem of the initial post.I will further check your idea and search for...
Thanks for your feedback. Interesting to hear that you worked in the 90's with FMCW radar's and saw the same problems.
Hello CedronThanks for sharing your ideas and for your great feedback. I will study it in more detail and try to implement it in the end application.
Hello DanThanks for sharing the two documents. I was not aware of the TI paper what clears up a lot between the differences of both architectures.
Hello CedronYou're right it makes sense that I share some real world data. We sample the time domain signal after the real baseband mixer. We are using a highpass...
Hello bloublouWe are using a windowing in the end application but see the same effect there for low frequencies.As mentioned above our end application is an FMCW...
Hello DanInteresting input, thank you very much. We will study it in more detail in combination with the feedback of Cedron.
Hello CedronThanks for linking your blog posts in this and also the other reply. They are great but I need more time to dig deeper here.Maybe you're exact formulas...
Thanks for your reply and yes you are right we are working with real-valued sinusoids.The end application is an FMCW radar where we have no option to use a complex...
