Paper Abstract

Estimation of the specular sea-reflection coefficient is carried out while simultaneously tracking a low-flying target with an `Extended Kalman Filter'. The error in the determination of target elevation is reduced by compensating the measurement for the corruption caused by the multipath reflection using an estimate of the sea-reflection coefficient. By this method it is possible to greatly reduce the resulting elevation errors in situations of low noise and gentle maneuvers. Higher levels of noise or large maneuvers can lead to sudden loss of track rather than to a moderate degradation of accuracy in the height determination. The causes of this degradation are explored.
