A new technique to measure noise parameters for global 21-cm experiments
Danny C. Price, Cheuk-Yu Edward Tong, Adrian T. Sutinjo +2
Radiometer experiments to detect 21-cm Hydrogen line emission from the Cosmic Dawn and Epoch of Reionization rely upon precise absolute calibration. During calibration, noise gener…
Measuring Noise Parameters Using an Open, Short, Load, and 1/8-wavelength Cable as Source Impedances
Danny C. Price, Cheuk-Yu Edward Tong, Adrian T. Sutinjo +2
Noise parameters are a set of four measurable quantities which determine the noise performance of a radio-frequency device under test. The noise parameters of a 2-port device can b…
System equivalent flux density of Stokes I, Q, U, V of a polarimetric interferometer
A. T. Sutinjo, D. C. X. Ung, M. Sokolowski
We present the system equivalent flux density (SEFD) expressions for all four Stokes parameters: I, Q, U, V. The expressions were derived based on our derivation of SEFD I (for Sto…
What is the SKA-Low Sensitivity for Your Favourite Radio Source ?
M. Sokolowski, S. J. Tingay, D. B. Davidson +8
The SKA will be the largest radio astronomy observatory ever built, providing unprecedented sensitivity over a very broad frequency (50 MHz to 15.3 GHz). The SKA-Low (50 - 350 MHz)…
System equivalent flux density of a low-frequency polarimetric phased array interferometer
A. T. Sutinjo, D. C. X. Ung, M. Sokolowski +2
This paper extends the treatment of system equivalent flux density (SEFD) in Sutinjo, A. T. et al. (2021) (Paper I) to interferometric phased array telescopes. The objective is to…
System Equivalent Flux Density of a Polarimetric Tripole Radio Interferometer
A. T. Sutinjo, M. Kovaleva, Y. Xu
System equivalent flux density (SEFD) is an important figure of merit of a radio telescope. This paper aims to derive a general expression for SEFD of a polarimetric tripole interf…
