Transmission code optimization method for incoherent scatter radar

When statistical inversion of a lag profile is used to determine an incoherent scatter target, the posterior variance of the estimated target can be used to determine how well a certain set of transmission codes perform. In this work we present an incoherent scatter radar transmission code optimization search method suitable for different modulation types, including binary phase, polyphase and ...

New Incoherent Scatter Radar Measurement Techniques and Data Analysis Methods

This dissertation presents new incoherent scatter radar measurement techniques and data analysis methods. The measurements used in the study were collected by connecting a computer-based receiver to the EISCAT (European Incoherent SCATter) radar on Svalbard. This hardware consists of a spectrum analyzer, a PCI-bus-based programmable digital I/O card and a desktop computer with a large-capacity ...

Meteoric dust effects on D-region incoherent scatter radar spectra

We extend the incoherent backscatter radar equation for the weakly ionized, collision-dominated case to include polydisperse charged dust, using the fluid-equation approach. Calculations with this equation show that the main effect of charged dust on the radar Doppler spectrum is to narrow it, except in the case of very small, negatively charged dust, which widens the spectrum. The results are ...

Substorm Triggering by New Plasma Intrusion: Incoherent-Scatter Radar Observations

In the companion paper, we identified a repeatable sequence of events leading to substorm onset in THEMIS all-sky imager observations: enhanced flows bring new plasma into the plasma sheet. The new plasma then moves earthward as a flow channel, bringing it to the near-Earth plasma sheet and where it produces onset instability. New plasma entering the dusk (dawn) convection cell drifts equatorwa...
