DIY SAR Radar


#1

Hello ,

I want to take mountain pictures without limitation of film , camera or
lens
size and expense.
I want to know that how can I create the most basic sar receiver
transmitter
combination for that purpose.
I found satellite receivers or ham radio gunnplexer based transreceivers
are
cheap but I dont know they are for that purpose .

Best regards ,

I’d start with some textbooks that cover Synthetic Aperture Radar.
Artech House has lots of expensive books to choose from :wink:

And of course google.

This will be extremely challenging. Synthetic Aperture Radar is much
more complicated than say, pulsed-Doppler radar. Whereas, pulsed-Doppler
radar can be explained in a few minutes, SAR cannot. In fact, the
nuances of SAR take most people quite sometime to understand.

In addition to very strict radar transmitter and receiver requirements,
you must have accurate aircraft positioning information to make the
algorithms work (less than 1/8 of a wavelength in most cases).

With that said, if you choose to continue with this project, I will be
very interested to learn of your progress.
