Abstract:

The prediction model of the radar maximum detection range of the sea surface ship in evaporation duct environments is studied. The predictions of the present radar Over The Horizon detection range prediction model frequently deviate significantly from radar measurements. The limitation of the present prediction model is described. The use of the vertical multi-scatter center to model the surface ship is presented. A vertical distribution model of the radar cross section is used to correct the present prediction model. Finally, the predictions by the corrected model are compared with the radar observations. The result shows that the predictions by the corrected model agree well with the observations and are more accurate.

Key words: evaporation duct, radar, maximum detection range, multi-scatter center
