I How Can Measured Satellite Magnitudes Be Converted to Radiant Intensity?

Click For Summary
To convert measured satellite magnitudes into radiant intensity, integrating the solar spectrum over the filter bandpasses is essential to determine the visual magnitude of the sun in each filter. This solar magnitude can then be used alongside the satellite's magnitude to calculate its radiant intensity. The discussion highlights the need for clarity on the specific relationships and equations required for this conversion process. Participants seek guidance on the correct methodologies to achieve accurate results. Understanding these relationships is crucial for effective radiant intensity calculations.

TL;DR
Asking how I would convert measured magnitudes to radiant intensity.
I have the measured magnitudes of a satellite object in four filters and I want to convert this into into Radiant Intensity. I was told that if I integrated the solar spectrum over my filter bandpasses , I could obtain the visual mag of the sun in each of these filters and use this to obtain the RI of the satellite (knowing the satellite mag), However I am unsure of the correct relationships/equations needed to do this.

Any help would be appreciated.
 

Thread 'Project Progress Report and possible Radio Astronomy Technique?'

Some 8 years ago I posted some experiments using 2 Software Defined Radios slaved to a common clock. The idea was measure small thermal noise by making correlation measurements between the IQ samples from each radio. This is a project that has kinda smoldered in the background where I've made progress in fits and starts. Since most (all?) RA signals are small thermal signals it seemed like the technique should be a natural approach. A recent thread discussing the feasibility of using SDRs to...
