First Claim
Patent Images
1. A method, comprising:
- computing, using a processor, sea clutter threshold bias values as a function of range and azimuth;
receiving a first shape corresponding to a first region of sea clutter about a radar;
combining the sea clutter threshold bias values with the first shape to provide non-isotropic sensitivity time control (STC) for the radar; and
outputting radar return for display with sea clutter suppressed in the first shape.

Abstract
Methods and apparatus to provide computing, using a processor, sea clutter threshold bias values as a function of range and azimuth, receiving a first shape corresponding to a first region of sea clutter about a radar, combining the sea clutter threshold bias values with the first shape to provide non-isotropic sensitivity time control (STC) for the radar, and outputting radar return for display with sea clutter suppressed in the first shape.

9. A method, comprising:
-
outputting display information for a radar including sea clutter with sensitivity time control (STC) off; receiving a first shape corresponding to a region of sea clutter displayed with the STC off; computing, using a processor, sea clutter threshold bias values for range and azimuth to provide non-isotropic STC; and outputting for display radar return information with sea clutter suppressed in the first shape using the sea clutter threshold bias values. - View Dependent Claims (10, 11)

12. A radar system, comprising:
-
an antenna to receive radar return; an sensitivity time control (STC) module to provide STC processing of the radar return, the STC module including a sea clutter module to compute sea clutter threshold bias values as a function of range and azimuth; a user interface to enable a user to interact with the radar including to receive a first shape corresponding to a first region of sea clutter about the radar; a display to enable a user to perceive radar return information; a processor to combine the sea clutter threshold bias values with the first shape to provide non-isotropic sensitivity time control (STC) for the radar, and output radar return on the display with sea clutter suppressed in the first shape. - View Dependent Claims (13, 14, 15, 16, 17, 18)
