Phased.LinearFMWaveform Function + For Loop
显示 更早的评论
I am trying to generate a Phase.LinearFMWaveform, as a function of a set of some particular, varying parameters. To be specific, I would like the parameters PulseWidth, PRF (Pulse Repetition Frequency), and NumPulses. (These are specific arguments that Phase.LinearFMWaveform adhere to.) I would also like to vary the Amplitude.
Basically, with each iteration of the For loop, I would like a different Phase.LinearFMWaveform to generate.
SampRate_LFM = 1e6
SweepBW_LFM = 1e5
NumRepPulse_LFM = 1
MinPW_LFM = 40e-6
MaxPW_LFM = 60e-6
MinPRF_LFM = 5e3
MaxPRF_LFM = 10e3
MinAmp_LFM = 1
MaxAmp_LFM = 5
NumRepPulse = 4
NumPulse_LFM = 1
for k = 1: NumRepPulse_LFM
PW_LFM(:, k) = round((MinPW_LFM + (MaxPW_LFM - MinPW_LFM)*rand(1))/NumRepPulse, 6, 'decimals')*NumRepPulse % generate a set of varying PWs
PRF_LFM(:, k) = round(MinPRF_LFM + (MaxPRF_LFM - MinPRF_LFM)*rand(1)/NumRepPulse, 1, 'significant')*NumRepPulse % generate a set of varying PRFs
Amp_LFM(:, k) = round(MinAmp_LFM + (MaxAmp_LFM - MinAmp_LFM)*rand(1)/NumRepPulse, 1, 'significant')*NumRepPulse % generate a set of varying Amps
LFM = phased.LinearFMWaveform('SampleRate', SampRate_LFM, 'PulseWidth', PW_LFM(k), 'PRF', PRF_LFM(k), 'SweepBandwidth', SweepBW_LFM, 'NumPulses', NumPulse_LFM)
end

Your code runs just fine, could you elaborate what your question is? My guess is you want to see the signal itself? If so, you can just call the step() method after you created LFM, like
x = step(LFM)
