What are the frequencies here ? Can it all be done with SDR ?

- zeeed 3y agohttps://arxiv.org/pdf/2311.16024.pdf https://arxiv.org/pdf/2311.16024.pdf Yes, their POC uses SDR
- derstander 3y agoAs the sibling comment from zeeed mentioned, yes — in this case. More generally maybe but not always. If you wanted to use a DRFM jammer to insert false targets in an imaging radar, the bandwidths required may be a challenge. There are commercial SAR satellite operators that you (for some definition of you — I personally couldn’t afford it) can buy from that sell imagery that’s got a resolution of 0.5 meters per pixel. That would require a bandwidth of about 300MHz. I haven’t looked at the SDR landscape in awhile but when I did that was sort of sporty — by that I mean >300 complex megasamples a second (for Nyquist, not including any oversampling). And that would be after basebanding in analog before sampling to digital.
