The Radar mounted on a ship for surveillance purposes and its target detection performance is based on the parameters, Signal to Noise Ratio (SNR), probability of detection (Pd) and track confirmation and maintenance which is dependent on Track confidence level. Primarily, radar target detection, track initiation and track maintenance is dependent upon plot consistency over range and azimuth. Naval surveillance radar performance will be significantly affected due to the sea state experienced by the Ship in terms of roll and pitch parameters. The radar performance is affected due to roll and pitch of the Ship, which significantly results in degraded target detection and tracking. The Roll and pitch of ship induces a dynamic sinusoidal effect in terms of systematic azimuth offset (skew) and elevation offset, which leads to incorrect range and bearing declarations for targets apart from coverage loss.

Keywords- Signal to Noise Ratio, Track confidence level, azimuth offset, elevation coverage, bearing
