is there a function 'helperRadarPulsePlot(rxpulses,threshold,... fast_time_grid,slow_time_grid,num_pulse_plot);' in matlab 2013a
显示 更早的评论
when i am running helperRadarPulsePlot(rxpulses,threshold,... fast_time_grid,slow_time_grid,num_pulse_plot); i get an error message
Undefined function 'helperRadarPulsePlot' for input arguments of type 'double'.
Error in try1 (line 119) helperRadarPulsePlot(rxpulses,threshold,...
how can i solve it

There is a problem with class of the input. Seems the function wont accept double.

Upgrade to at least R2013b.

No, there is not.
It was new in R2013b, and was not present in R2013a.

It just does a bunch of plotting. Comment it out and go on.

It is also used in ChirpRangeEstimationExample
The R2013a equivalent function appears to be named rangedemoplotpulse and the R2013a version of the code is at http://www.mathworks.com/help/releases/R2013a/phased/examples/designing-a-basic-monostatic-pulse-radar.html

I think it is a BUG, so I write the funciton for it.
function helperRadarPulsePlot(pulses,threshold,fgrid,~,num_pulse_plot)
for n=1:num_pulse_plot
subplot(num_pulse_plot,1,n);
plot(fgrid,20*log10(abs(pulses(:,n))),'b','LineWidth',2);hold on;
plot(fgrid,10*log10(threshold)*ones(1,size(pulses,1)),'-.r','LineWidth',1);hold off;
xlabel('Time (s)');
ylabel('Power (dBW)');
title(['Pulse ',num2str(n)]);
end
end

Thanks for this function. It works nicely for me.

This is a helper function used in the example of Designing a Basic Monostatic Radar. The example ships in R2013a so you should be able to find the corresponding helper function used in that release.
