Remote EMI Field Strength Mapping, Phase II

Completed Technology Project

Project Introduction

Remote EMI Field Strength Mapping, Phase II
NASA often must deal with the issue of protecting EMI sensitive payloads and instrumentation from damage due to radiated energy. Many of these EMI sensitive payloads can be damaged by seemingly benign sources such as communication networks or microwave ovens. The problem becomes more difficult when these sensitive payloads and instrumentation require movement from one location to another. It is extremely difficult and time consuming to identify and characterize the potential threat to these payloads with current tools and techniques. Soneticom proposes to utilize a small network of sensors to quickly and efficiently identify and locate sources of EMI radiation. Once the source is located Soneticom will utilize available signal parameters such as Received Signal Strength (RSS) at each sensor to estimate the signal strength at any point within the network's coverage area. Figure 2.1 is a conceptual diagram of how this innovation might look once displayed on a map. Soneticom will utilize the existing Lynx Geolocation platform which has the capability to identify and locate an EMI radiation source in the 20 MHz - 30 GHz range. The Lynx system will provide the hardware platform to develop algorithms required to estimate the signal strength across the network's coverage area More »
