Radio frequency interference measurement in site testing programs for the future multi-wavelength observatory in Indonesia
Abstract
A new multi-wavelength astronomical observatory in Indonesia is currently under preparation. To pave the way the presence of radio astronomical facilities in the planned observatory, we conduct a series of radio frequency interference (RFI) measurements as part of its site testing programs. The corresponding sites, instruments as well as its measurement set up must be selected, planned, and implemented accordingly. This work presents our preparation set up and considers the RFI measurement at meter and centimeter wavelengths (or frequencies from 50 MHz up to 6 GHz). In this frequency range, it is relevant to adopt the Square Kilometre Array (SKA) Protocol as our measurement method. The first results using the Mode 1 of the SKA Protocol are used as reference in this work. Preparation of the Mode 2 is currently undertaken and its preliminary results are presented.
