Two frequency widebeam riometer, any useful sources?

[franken35]

Hi, my MSc project work is designing and building two frequency widebeam riometer. I have never worked in this area. Do you know any useful sources or even previous designs. I have found just the first riometer designs (1951-53), but obviously I need something much more new then that. Thanks in advance

Re: Analogue riometer design

Hello karesz,

Thank you for information. I do admire your enthusiasm of google. That is almost the first resourse I tried. However I found a lot of information on measurements, physics and imaging riometers. But not much on widebeam riometers designs in particularly.

"linkinghub.elseviere.com/retrieve/pii/S0273117706000494"

The link above I cannot access for some reason.

Regards,
Frank

Analogue riometer design

Hallo Frank,
Im not a super fun from it, but is good to use...
Im sorry, I dont tell it for you; on what a link I become these item:-(...
The sentence "The riometer before 18:00 is based on the wide-beam riometer at Abisko" was their title, but my PC, at home, can not find some similar with it, may be in the firm on monday...
If you cant find some practicable infos, you must in short time & more times repeat your searches; the search engines will collect more data over frequently searched subjects

Re: Analogue riometer design

Thanks again, I appreciate you help. However as I said its only background information. A little information about widebeam riometers, but nothing on its hardware analogue design. There are a few links on design, but the are restricted on few websites.
