Radar Echo Enhancement Using Surface Reflections
Abstract
Analysis and simulation have shown that the detection of targets by pencil-beam radars could be enhanced by using strong surface reflections which are sometimes present. The radar used a beam pointed at the target and a beam pointed at the target reflection on the surface. Transmitting only on the direct beam and simultaneously receiving the direct and reflected beam energy, up to 2. 5 dB improvement in signal-to-noise ratio (S/N) was obtained. During strong reflecting conditions, transmitting and receiving simultaneously over both beams made up to 5.5 dB improvement in S/Ns, but the improvement and occasional loss depended heavily on the target location within the beam.
