The surveillance system is based on a flexible, multimode radar, which enables AWACS to separate maritime and airborne targets from ground and sea clutter radar returns.
The sea clutter filter enables the Doppler signal-processing unit to filter out sea wave clutter returns in both velocity and amplitude.
Next, we turn off the unit's rain clutter and sea clutter filters.
With its sophisticated filters installed to counter sea clutter and its ability to operate in high temperatures, Northrop Grumman's TPS-78 and TPS-703 radars are ideally suited to the unique environment of the Gulf.
After describing the experimental evidence of sea clutter characteristics, he presents three chapters that discuss modeling radar scattering, statistical models of sea clutter, and the simulation of clutter and other random processes.
The sea state is such that a periscope will be difficult to detect among the sea clutter.

Each new 4- and 6-foot open-array scanner features automatic and manual sensitivity and tuning controls, including gain, sea clutter, and rain clutter - which allows users to spend less time tuning the unit and more time navigating.
Deployed by high mobility trucks, the C-130 Hercules aircraft-transportable next-generation radar is compatible for use in mountainous and coastal regions, because of its ability to detect small, low-altitude targets in heavy ground and sea clutter.
