Taking into account the existence of multipath ionospheric propagation (MIP), a typical phenomenon that skywave over-the-horizon (OTH) radar may encounter, this paper develops the received signal model for a non-point target for multiple-input multiple-output skywave over-the-horizon (MIMO-OTH) radar using the most well accepted physics-based model of the ionosphere. The signal model describes the...
Consider a multiple-input multiple-output skywave over-the-horizon (MIMO-OTH) radar system withM transmit and N receive antennas employing the conventional optimal detector for a single complex Gaussian target. The signal from the mth transmit antenna reaches the target after being reflected by the ionosphere via Qm ray paths. Each of these multipath signals bounce off the target and reach the nth...
Ionospheric information is required when estimating target parameters in skywave over-the-horizon (OTH) radar. Unlike the traditional OTH radar which uses only the measurements of ionospheric parameters obtained from an ionosonde to estimate the target parameters, the multiple-input multiple-output skywave OTH (MIMO-OTH) radar studied in this paper estimates the ionospheric and target parameters jointly...
Exploiting the received signals, which are usually not employed in the traditional OTH radar for ionospheric parameter estimation, we study joint estimation of target and ionospheric parameters for multiple-input multiple-output skywave OTH (MIMO-OTH) radar. We employ a parabolic layer model to characterize the ionospheric distortions. We model the target and ionospheric parameters as deterministic...
