A Multidimensional Characterization of MUIR Backscatter Spectra Resulting from Ionospheric Heating Experiments Performed at HAARP
… ionospheric heating features by varying HF aspect angle, HF pump frequency, UHF pointing angle, and heating pulse time. Through the use of the HAARP HF array and the MUIR UHF radar, we observed cascade (LDI), collapse (cavitons), parametric decay lines (PDI), outshifted plasma lines …

Reconfigurable Resonant Cubic HF Phased Array for In-Space Assembly Operation
Conventional two-dimensional phased arrays face two major shortcomings: the presence of ambiguities in direction of arrival measurements and beam broadening endfire effects. The literature provides methods for addressing and minimizing these problems on conventional planar phased array structures, …
