Joint Estimation of MIMO-OTH Radar Measurements and Ionospheric Parameters

IEEE Transactions on Aerospace and Electronic Systems, 2017
To avoid the disadvantage of the traditional over-the-horizon (OTH) radar, which uses only the measurements of ionospheric parameters obtained from an ionosonde to estimate the target parameters, this paper proposes a new multiple-input multiple-output skywave OTH radar, which estimates the ionospheric and target parameters jointly by exploiting the ...

Nostradamus: An OTH Radar

IEEE Aerospace and Electronic Systems Magazine, 2006
ONERA, funded by the French Ministry of Defence has conducted the realization and experimentations of the Doppler Skywave OTH radar called NOSTRADAMUS. One of the main characteristics of Skywave OTH radar is the dependence to the ionosphere for successful operation.
