Spectral-selective radiometers with bandwidths of up to 1 GHz
Spectral-selective radiometers, ensuring high-accuracy measurements in continuum under exposure to narrow-band radio-interferences and detection of radio-wave radiations in spectral lines, are described. Two parallel channels of the radiometer simultaneously receive signals of two polarizations or s...

Summary: | Spectral-selective radiometers, ensuring high-accuracy measurements in continuum under exposure to narrow-band radio-interferences and detection of radio-wave radiations in spectral lines, are described. Two parallel channels of the radiometer simultaneously receive signals of two polarizations or signals of two wave bands. The channels of the radiometer installed at the Badary observatory operate in frequency bands of up to 32 MHz and have a resolution of 62.5 kHz, if the reception band is at maximum. The channels of the radiometer at the Svetloe observatory have reception bands of 1024 or 512 MHz and a resolution of 1.0 or 0.5 MHz, respectively. |
