Noise Parameter Measurement and Its Application in Receiving Phased Arrays for Low-Frequency Radio Astronomy

The noise temperature of a phased array is a function the noise parameters of the low-noise amplifiers connected to the antenna elements. However, noise parameters at low-frequency radio astronomy bands (below few hundred MHz) are not usually readily available. We discuss the significance of noise p...

Description
Summary:The noise temperature of a phased array is a function the noise parameters of the low-noise amplifiers connected to the antenna elements. However, noise parameters at low-frequency radio astronomy bands (below few hundred MHz) are not usually readily available. We discuss the significance of noise parameters in phased arrays and demonstrate a low-cost option for noise parameter extraction.
