Okay, well best of luck with that. I hope the B200 has the necessary capabilities to do what you need. Here are the links to block writing, hope this helps. https://wiki.gnuradio.org/index.php/OutOfTreeModules https://wiki.gnuradio.org/index.php/BlocksCodingGuide Thank you, Alex On Fri, Jul 9,

Yes, I use it for another project which is a pulse FMCW radar project In this project, we need an LFM with receiving time (dead-time) for testing the function of the radar (transmitter and receiver etc..) Do you have any tutorial to modify the block of GNU Radio? I am a hardware guy so it may tak

What on the other device are you trying to measure? Are you simply attempting to see if you can receive a signal, or are you trying to receive information of some kind? Generating an LFM signal is no problem, and modifying the source code is a good way to go if that's all you want to do. You are r

Thank Alex for your answer, For the second question, I will not design a pulse doppler radar with a linear FM pulse. But I wonder that I could generate an LFM signal (to measure another RF device at 1GHz) using Ettus B200? Due to the limit of the hardware capabilities, I think I can only generate

Hello, It has been a while since I used the FMCW block in the Radar toolbox, but from what I can remember, the three samples sections are defining the percentage of the signal you want distributed in each of those sections. For example, if you want 50% of your signal to be CW, and 50% to be up-chi

Hello all, I want to make an FMCW signal generation with GNU Radar toolbox and Ettus B200 I saw that you have several examples in https://github.com/kit-cel/gr-radar/tree/master/examples/simulation, but I do not understand the following parameters of the FMCW block - Samples CW - Samples up-chirp -
