An Atmospheric Noise Model with Application to Low Frequency Navigation Systems

Abstract

A prerequisite of the design of low frequency radio receivers is a model for low frequency atmospheric radio noise that encompasse the non-Gaussian nature of the actual noise process and is sufficiently tractable to enable performance analysis and optimization of receiver designs. This work describes a new model for atmospheric noise waveforms observed at the output of the antenna bandlimiting filter. This model, which is based on statistical analysis of sample records of these waveforms, is used to analyze the performance of typical radio navigation receivers and to determine near optimum receiver performance. The analysis is verified by simulating the receiver structure and testing the receiver with the actual noise sample records.
