Detection of Slow Radial Velocity Ship by OTHR

In order to detect ship in the spread sea clutter caused by ionospheric disturbance, algorithms of short coherent integration time (CIT) are used in over-the-horizon radar system. Here, ECVC (Estimate Clutter Via Correlation) algorithm is employed to provide higher resolution to detect ship of slow radial velocity. The following two topics are discussed: (1) the model of sea clutter and ECVC algorithm; (2) the detection results of ECVC, compared with Root, SVD (Singular Value Decomposition) and EVD (Eigen-Value Decomposition). Simulation and experiment results demonstrate the usefulness of the proposed approach.
