Description
show(
shows the
display window of the sIS
)phased.IntensityScope

.
Input Arguments
sIS
— Intensity scope
phased.IntensityScope
System object™
Intensity scope, specified as a phased.IntensityScope
System object.
Example: phased.IntensityScope
Examples
Hide and Show Intensity Scope
Create an angle-time-intensity scope. Use the phased.IntensityScope
System object™ to display simulated intensity as a function of the angular motion of a moving target. After five steps in the processing loop, use the hide
method to hide the scope. At completion of the loop, use the show
method to show the scope.
Simulate data for 5 seconds with a time interval of 0.5 seconds between scan lines.
nsteps = 10; dt = 0.5; timespan = nsteps*dt;
Set Up IntensityScope System Object
Create an angle-time-intensity scope having azimuth angle bins spanning −180° to 180° with 1° resolution.
scanline = zeros(361,1); angres = 1.0; angmin = -180.0; angmax = 180.0; rtidisplay = phased.IntensityScope( ... 'Name','IntensityScope Display',... 'Title','Azimuth vs. Time',... 'XLabel','Azimuth (deg)', ... 'XResolution',angres,'XOffset',angmin,... 'TimeResolution',dt,'TimeSpan',timespan, ... 'IntensityUnits','Watts',... 'Position',[100,100,800,450]);
Loop Over Scan Updates
Simulate angular motion and fill the bin containing the current angular position of the signal. Hide the scope after the 5th step and show the scope at the end of the simulation.
for k = 1:nsteps ang = -130.0 + k; binindexdx = floor((ang - angmin)/angres) + 1; scanline(binindexdx) = 1; rtidisplay(scanline); scanline(binindexdx) = 0; if k == 5 hide(rtidisplay) end pause(.1); end show(rtidisplay)
