Abstract

Magdalena Ridge Observatory Interferometer (MROI) is a ten telescope optical interferometer array being built on the Magdalena Mountains 20 miles west of Socorro, New Mexico. A Radio Frequency (RF) survey in the 100 MHz to 3 GHz RF band has been conducted at the site of the interferometer array on the ridge. The RF site characterization plan is to conduct a pre-construction RF survey and document the existing RF background. A post-construction RF survey will also be conducted after installation and commissioning of the MROI to understand quantitatively any changes to the RF environment at the site. This paper describes the instrumentation and methods used for the RF survey and the results obtained to date. With Langmuir Laboratory for lightning research, MRO 2.4m Telescope co-located on the mountain and with the Very Large Array and the White Sands Missile Range facilities also near by; these data are presented as they may be useful for them and other facilities in future. The RF survey is also proposed as a useful tool to better design MROI facility with knowledge and understanding of the environment for RFI/EMC control and mitigation.
