The MAtrix Radiometric System project is intended to design more or
less simple, but effective radiometric support to the
|
Parameters of the resulting radiometric receiver were as follows: |
The overall dimensions of the radiometric module are 13x24x59 mm and of the noise generator module are 13x24x29 mm. The input waveguide window is for WR28 waveguide. MARS-1 radiometric module investigated at the laboratory at three different modes of operation: total power, noise-added ( NAR ) and switched mode. As a result of test, only the last mode was accepted for future application, as the stability of the switched radiometer was about of the order of magnitude better ( or, in other words, 1/f knee frequency was correspondingly lower ), than for other modes. The first MARS-1 radiometric module was tested at the RATAN-600 radio telescope completed with it's regular radiometers. The result ( atmospheric radio emission recording ) is shown in the figure 3. ![]() Figure 3. Atmospheric radio emission at four wavelengths of RATAN-600.
