摘要

我们正在探索在\({\approx }\) 11.2 GHz （\({\lambda }=2.68\) cm）的太阳色球层进行无线电干涉观测的可能性，包括总强度（Stokes-I）和圆极化强度（Stokes-V），使用低成本的商用碟形电视天线。在这里，我们提出了我们的磁场强度(B)的初步结果估计使用的数据与原型设置，并将其与类似的观察结果进行比较。

A prototype radio interferometer system with commercial dish TV antennas for observations of the solar chromospheric magnetic field

We are exploring the possibility of carrying out radio interferometric observations of the solar chromosphere at \({\approx }\) 11.2 GHz (\({\lambda }=2.68\) cm), in both total intensity (Stokes-I) and circularly polarized intensity (Stokes-V), using low-cost commercial dish TV antennas. Here, we present our initial results on the magnetic field strength (B) estimated using data obtained with a prototype set-up, and compare them with similar observations.
