Harbor control search processing for detection of slow moving ships in adverse conditions

Abstract

Two land based harbor control search signal processors are numerically evaluated using actual recorded sea clutter data which contain different weather conditions, sea states, and various degrees of land background. The first processor is based on an inverse digital MTI (IDMTI). The second approach forms a series of narrow band filters across the clutter region. The detection performance using both actual and calibrated targets is also quantified.
