Abstract

<abstract abstract-type="main"> <title>Abstract</title> <p id="rds20034-para-0001">[1] The ISIS array (Intercepted Signals for Ionospheric Science) is a distributed, coherent software radio array designed for the study of geospace phenomena by observing the scatter of ambient radio frequency (RF) signals. ISIS data acquisition and analysis is performed using the MIDAS‐M platform (Millstone Data Acquisition System ‐ Mobile). Observations of RF signals can be performed between HF and L‐band using the Array nodes and appropriate antennas. The deployment of the Array focuses on observations of the plasmasphere boundary layer. We discuss the concept of the coherent software radio array, describe the ISIS hardware, and give examples of data from the system for selected applications. In particular, we include the first observations of <italic>E</italic> region irregularities using the Array. We also present single‐site passive radar observations of both meteor trails and <italic>E</italic> region irregularities using adaptive filtering techniques.</p> </abstract>
