Thank you very much, this has greatly enhanced my knowledge. Please links in the caption are not going through, I also wish to get the slides, or a document i can exploit more of the information detailed in this tutorial from.
Thanks. Great series. I started with no knowledge and you taught this so well I now understand the basics. I also understand more of what I dont know. Well done on a great presentation.
Such a brilliant video, I've learned a lot. But I wonder if there is a cut at 2:20. I'm very curious about WHY are these two expressions off by a factor of 2 ?
In the first case, the differential distance affects the round-trip (to and fro to the target). In the second case the differential distance is only one way (from the target to a specific antenna)
- In first case, the difference in time translates to the difference in round-trip distances, so delta_T = 2*delta_D/c (distance/velocity). The differential distance is measured across 2 consecutive chirps. - In the second case, the difference in time translates to difference in distance travelled by the radar waves to get to Rx antenna 1 and antenna 2, so delta_T = delta_D/c (where delta_D is the additional distance the radar wave has to travel to reach the farther antenna). The differential distance is measured during the same chirp but is a function of the distance/separation between the antennas.
