I'm looking at the datasheet for the analog devices hmc431lp4 voltage controlled oscillator, and I can't tell if its output waveform is a sine wave or square wave. The datasheet doesn't label the oscillator as being harmonic or relaxation. I'm wondering because I am trying to understand a homemade radar system I found online. Do FMCW systems like this project require a sinusoidal RF signal to operate?

I don't know the answer but the harmonics figures should give a clue. I notice that it is rated at > 500 W which, I suspect, should be mW.

So because the datasheet includes information on output harmonics the oscillator most likely produces a sinewave?

I would think so. A squarewave wouldn't have any even harmonics, only odd.

This VCO outputs a frequency between 5.5 and 6.1 GHz.
It is sort of "implied" that the output signal will be a sinewave because:
a "decent" square wave at that frequency would need a signal bandwidth of several hundreds of GHz. That's because a square wave relies on harmonic frequencies (multiples of the base frequency) to become "square". Read up on Fourier analysis to understand this
this chip is designed to be used in RF transceivers, usually as a local oscillator for mixing up/down RF signals. This works best using sinewaves as RF designers want one frequency to deal with, not one frequency and all its harmonics (like a square wave would have).
