[Phased Array Toolbox] Modelling an unmodulated continuous wave radar

I have sourced the Matlab's Phased Array Toolbox documentation but I could not find how one can model a continuous and unmodulated wave signal. What I would like to model is a very simple radar whose' transmitter frequency does not change in time.

Anyone knows how this can be achieved?

A radar system is probably modulated. Since the modeling is done in baseband, for a single frequency continuous wave, that will be a simple sequence of ones. Although the toolbox doesn't have a specific waveform component for that, I think you can probably just use phased.RectangularWaveform and set the PRF property to the inverse of the sweep time and set the PulseWidth property to the sweep time.

This may be a trivial question but, wouldn't that result in a waveform with a frequency of 0 Hz? How would you convert, or modulate, that to a continuous wave of say 200 MHz?
