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.
