The dashed vertical lines indicate the locations of Wcpthe frequency where the phase margin is measured, and Wcgthe frequency where the gain margin is measured.

When two or more radar systems are close to each other and you want to reduce interference among them. When digital processing suggests using a waveform with a discrete set of phases. For example, a Barker-coded waveform is a bi-phase waveform. Conversely, you might use another waveform instead of a phase-coded waveform in the following situations:. To create a phase-coded waveform, use phased.

Find the phase angle of the spiral from the x - and y -coordinates using the atan2 function. Note that this plot has discontinuities.

For such systems, the notion of disk margins provides more reliable estimates of the true gain and phase margins. Specify the dim argument as 1. Frequencies, specified as a vector. When you use margin mag,phase,w , margin relies on interpolation to approximate the margins, which generally produce less accurate results.
