Syntax

coeff = getMatchedFilter(waveform)
coeff = getMatchedFilter(waveform,FrequencyOffset = foffset)

Description

coeff = getMatchedFilter(waveform) returns the matched filter coefficients coeff for the pulse FM waveform object.

example

coeff = getMatchedFilter(waveform,FrequencyOffset = foffset) also specifies a frequency offset foffset when matched filter coefficients are generated. To enable this syntax, set the FrequencyOffsetSource property of the waveform to 'Input port'.

Open Live Script

Get the matched filter coefficients for a linear FM pulse.

waveform = phased.LinearFMWaveform('PulseWidth',5e-05,...
    'SweepBandwidth',1e5,'OutputFormat','Pulses');
coeff = getMatchedFilter(waveform);
stem(real(coeff))
title('Matched Filter Coefficients, Real Part')

Figure contains an axes object. The axes object with title Matched Filter Coefficients, Real Part contains an object of type stem.
