We present a numerical modelling approach for determining the HF radar cross-section of a volume displacement in the ocean surface. This displacement, for example, might be from a non-conductive wooden-hulled boat with no metal structure or fittings.

The paper highlights results from an electromagnetic modelling study into the properties of a two-dimensional transmitter array proposed by Riddolls for over-the-horizon radar in the polar region. The modelling indicates that the total radiated power

This paper considers the problem of increasing the sensitivity of the receiving system in an Over-The-Horizon Radar. We are concerned with the problem of detecting small targets in noise during night-time operation when reduced ionospheric propagatio

This paper demonstrated how a 2D planar oversampled HF receive array manifold can be modeled by NEC and utilized to asses the performance of conventional and optimal beamforming techniques. It is shown that the full EM array model behaves similar to
