I understand that sampling rate should be twice the signal bandwidth for successful reconstruction. But what I don't get is how this translates in the time domain. For example, I have a sine wave …

I have been reading about "all-digital" or "software-defined radars". Lately, I was trying to simulate an FMCW short range radar in Matlab. One thing that struck me during the simulation is that to ac …

consider the classic scenario of identifying a radar frequency. You typically have a very short pulse of very high RF frequency. For example, a 50ns pulse repeating itself every 1MHz or so (PRF 1MHz a …

(baseband) pulse bandwidth can be as large as 500MHz. To digitize this signal, you need high-speed ADCs, typically 1GHz sampling frequency. As far as I know, these ADCs are not cheap. Now, if you have …
