| مستخلص: | In this study, the electron number density is characterized through data from static rockets firings. A model of the plume in finite difference time domain (FDTD) simulations also supports the results. Radio frequency and radar methodologies are used to characterize the plume as a dynamic component of an electrical system, supported by the construction of an RF apparatus that includes the design and manufacture of ultra-wideband antenna arrays. The research estimates electron number density using methods exploiting signal processing techniques in time and frequency domain, but the data suggests that other dynamic elements influence delay and attenuation of the radio signal. |
