    Very cool video! 1:48 That's also why pulsed lasers are able to to ablate material while being "only" 2W of average power

      yeah I mean 2W at 10% duty cycle or less is quite a bit!

    In sonar we have DELTIC delay line time compression. Auto correlation you can track a moving submarine with just two hydrophones. Used by CAPTOR smart mines in the late 70s. (Band limited white nosie from moving sub is XORed and accumulated). Way before the microprocessor was around.

    Nice! I would say that at 5:40 "beat" is better described as the difference in frequency between two signals than as the difference in frequency of one signal at different times.

    > FMCW radars often also have some "off" time between chirps
    That would not be FMCW, but FMOP.

      Yeah! This was a super basic intro to the technology so I didn't cover that, but yes there definitely is a gap many times - I included this in the caveats section of the description :) Thanks for watching!

    can you explain at 1:53 why we want to have a greater desired power ?

    • @MarshallBrunerRF
      @MarshallBrunerRF  2 месяца назад +1

      @@RUDRARAKESHKUMARGOHIL yeah! This isn’t always the case (for example automotive radar sometimes) but you want to increase average output power because the signal you transmit degrades as it travels through the air. So if you transmit a higher power, you can see farther distances in general. Hope this helps and thanks for watching!
