Study of ELF Propagation Parameters Based on the Simulated Schumann Resonances

Yi Wang; Ye Zhou; Qunsheng Cao IEEE Antennas and Wireless Propagation Letters, 2014

The extremely low frequency (ELF) electromagnetic (EM) wave propagation parameters are obtained and studied based on the simulated Schumann resonances (SRs). To obtain the SRs, ELF EM wave propagation and EM environment of the Earth-ionosphere (E-I) system are rigorously simulated using the geodesic finite-difference time-domain (FDTD) method. Prony's method is introduced to analyze the simulation results for obtaining the SR ...

Progress toward a practical skywave sea-state radar

T. Georges IEEE Transactions on Antennas and Propagation, 1980

Recent advances in propagation modeling, ionospheric diagnostics, and signal processing have helped overcome the limitations the ionosphere imposes on sea- state measurements with HF skywave radar. Wind-direction fields in tropical storms can be routinely mapped under most ionospheric conditions, but waveheight and wave-spectrum extraction is more sensitive to ionospheric distortions and requires care in signal processing and in selecting an ...

Shane Lawrence 2011 XXXth URSI General Assembly and Scientific Symposium, 2011

Extreme electromagnetic anomalies in the ionosphere and and their future implications. There are many unusual and interesting anomalies in the ionosphere resulting from abnormal and even severe electromagnetic conditions. These anomalies are not often recognised as being any more significant than simply unusual. However they may have long term implications which should be considered in the light of the continually ...


VLF modes below a composite anisotropic ionosphere

J. Galejs IEEE Transactions on Antennas and Propagation, 1970

The TM and TE modes excited by horizontally and vertically polarized line sources are investigated for composite ionosphere models and for high- and low-ground conductivities. The daytime propagation characteristics are comparable to those of a simpler exponential model. In nighttime propagation, the TE2mode has a smaller perturbing effect than in simpler ionosphere models; the ratio of TE to TM field ...

  • SATNAV SIGNALS

    Satnav signals link the satellites to receivers in the user segment and the control segment. Like many other aspects of a satnav system, signals must be exquisitely engineered and carefully implemented in order for the system to provide the expected high levels of performance. This chapter provides an overview of signals and their mathematical representations, with an emphasis on direct-sequence spread spectrum (DSSS) signals and specific spreading modulations used for satnav. It introduces mathematical models for the effects of Doppler shift and propagation through the dispersive ionosphere. Satnav signals undergo Doppler shifts caused by a combination of satellite motion and receiver motion. The chapter provides a primarily qualitative discussion of satnav signal characteristics, identifying tradeoffs, and providing perspectives involving signal design choices. It then establishes the detailed mathematics of satnav signals, identifying characteristics, parameters, and models employed in descriptions of specific signals and in definition of receiver processing.
