System object: phased.FMCWWaveform
Package: phased

Plot FMCW waveform


h = plot(___)


plot(Hwav) plots the real part of the waveform specified by Hwav.

plot(Hwav,Name,Value) plots the waveform with additional options specified by one or more Name,Value pair arguments.

plot(Hwav,Name,Value,LineSpec) specifies the same line color, line style, or marker options as are available in the MATLAB® plot function.

h = plot(___) returns the line handle in the figure.

Input Arguments


Waveform object. This variable must be a scalar that represents a single waveform object.


Character vector to specifies the same line color, style, or marker options as are available in the MATLAB plot function. If you specify a PlotType value of 'complex', then LineSpec applies to both the real and imaginary subplots.

Default: 'b'

Name-Value Arguments

Specify optional comma-separated pairs of Name,Value arguments. Name is the argument name and Value is the corresponding value. Name must appear inside quotes. You can specify several name and value pair arguments in any order as Name1,Value1,...,NameN,ValueN.


Specifies whether the function plots the real part, imaginary part, or both parts of the waveform. Valid values are 'real', 'imag', and 'complex'.

Default: 'real'


Index of the sweep to plot. This value must be a positive integer scalar.

Default: 1

Output Arguments


Handle to the line or lines in the figure. For a PlotType value of 'complex', h is a column vector. The first and second elements of this vector are the handles to the lines in the real and imaginary subplots, respectively.

Create and plot an upsweep FMCW waveform.

waveform = phased.FMCWWaveform('SweepBandwidth',100.0e3,...

Figure contains an axes object. The axes object with title FMCW waveform: real part, sweep 1 contains an object of type line.
