Configuration Space Modeling

The standard method of generating realizations of ionospheric structure imposes the desired spectral characteristics by filtering white noise with the square root of the desired spectral density function (SDF).  The phase structure is purely random, which imposes a non physical … Continue reading

A Comparison of Phase Locked Loops and Frequency Hypothesis Tracking

Processing low orbiting beacon satellite data has been a challenge largely because of the limited vehicle space for a VHF, UHF, L-band antenna system. The effective antenna patterns severely limit range of uniform illumination range with a common phase center. … Continue reading

Digital Beacon Receiver Signal Processing

Chapters 1 through 4 of my book “The Theory of Scintillation with Applications to Remote Sensing” established an analytic and computational framework for understanding radio waves propagating through structure media, primarily the earth’s ionosphere.  From the time the book was … Continue reading

Wavelet Based Analysis of Ionospheric Data

Ionospheric diagnostics come from in-situ probes carried by rockets or satellites, forward propagation, and radar backscatter.  This blog entry addresses in situ measurements and remote sensing via forward radio propagation from satellite to ground propagation paths.  In situ measurements are … Continue reading

AGU 2013 Poster and Supplemental Material

Tomographic reconstruction of ionospheric electron density profiles from GPS satellite measurement is being used extensively for global ionospheric monitoring.  For the most part, the reconstruction process is a constrained iterative process.  The results are sensitive to errors and initial conditions.  … Continue reading

Phase Screen Models for Numerical Computation

To the extent that propagation disturbances can be approximated by an equivalent phase-screen, there are analytic models that allow computation of the power-spectrum of the intensity of the field as it propagates away from the phase screen.  The analysis involves … Continue reading
