Re: [arts-users] Combining simpleAMSU sensor response with antenna pattern

2022-01-06 Thread Patrick Eriksson 

Stuart,

No, met_mm does not support antennas. I just checked the code. Remember 
that we discussed antennas at some point, but don't remember if we had a 
plan for the antenna part. Can't say if it would be easy to add it. I am 
afraid that it could be complicated as we use antenna_dlos in a special 
way in met_mm. And going to 2D antennas I guess is out of the question.


Before I look at the details, can you explain a bit what you have in 
mind? to judge if met_mm is the right thing here? What will be critical 
for your simulations?


Bye,

Patrick

Hi Stefan,

Thanks for the pointer - I’d forgotten about the MetMM options and 
hadn’t considered that they might do what I need. However, I note that 
all the instruments in 
controlfiles/instruments/metmm/sensor_descriptions have the lines:


# Antenna is not supported for now

VectorSet( met_mm_antenna, [] )

Is this something that still needs to be implemented in ARTS, or have 
the controlfiles just not been updated yet?


Cheers,

Stuart

Dear Stuart, have you checked what is in the metmm folder? I think 
that's what you want.


Cheers

Dear ARTS community,

Is there a simple way to simulate a simple-AMSU-type sensor in ARTS,
but including an antenna pattern? The documentation for
sensor_responseSimpleAMSU says that it is only for pencil-beam
antennas. Initially I simply want to use a 1D Gaussian response, but
the FWHM beamwidth needs to be different for each of the channels
defined in sensor_description_amsu.

I’d appreciate any tips on the best way to do this!

Thanks in advance,

Stuart

Ups, sorry! My memory was wrong, I think. But copying in Alex just in case he 
has any comments.

Perhaps a stupid question: why do you want to include the antenna in a 1d case? 
Do you expect a significant effect towards the edge of the scan?

Best wishes,

Stefan
