- The sweep slope is the rate of change of frequency with respect to time during the frequency sweep of the LFM waveform.
- In LFM waveforms, the frequency increases or decreases linearly over time, resulting in a linear chirp. The bandwidth of the LFM pulse is determined by the total frequency span covered during the pulse duration.
- The sweep slope represents the rate of change of frequency over time, while the bandwidth represents the total frequency span covered by the pulse.
- In the “phased.RangeAngleResponse” function in MATLAB, the “SweepSlope” parameter should be set to the desired rate of change of frequency during the frequency sweep of the LFM waveform.
- The bandwidth and pulse width can be set independently using the appropriate parameters of the “LinearFMWaveform” object.

Below are the settings I'm using to create a phased.RangeAngleRresponse object. My assumption is the SweepSlope should just be the bandwidth of my LFM pulse divided by the pulse width. Is this a correct assumption?
response = phased.RangeAngleResponse(...
'RangeMethod','FFT',...
'SensorArray',MosaicArray,...
'OperatingFrequency',fc,...
'ElevationAngleSource','Property',...
'ElevationAngle',0,...
'SampleRate',fs,...
'SweepSlope',bw/tau,...
'ReferenceRangeCentered',false,...
'ReferenceRange',0,...
'RangeWindow','Taylor',...
'RangeSidelobeAttenuation',30,...
'DechirpInput',true);

Hi,
I understand that you want to know about “Sweep slope” parameter in the “phased.RangeAngleResponse” object.
Refer to the pointers explaining “sweep slope” parameter:
Please refer the documentation links attached below in order to get more information on “sweep slope”, bandwidth and pulse width.
