Continuous wave

And then the waveforms are either frequency or phase modulated.

If they're frequency modulated, it, it's called a FMCW radar, uh, frequency modulated continuous wave, and then if it's phase modulated, it's called a PMCW, a phase modulated CW radar.

Um, it- they have...

Overall, they have better properties than, uh, than pulse radar.

So the complexity basically shifts to the digital domain in DSP for the CW radar.

But that's okay because these days we have very capable compute platforms always with these robots, so we can handle complex DSP.

Uh, FMCW radar, uh, basically, uh, it's exactly like CTFM sonar.

So it, it sends these linear frequency chirps and uses those for ranging.
