Abstract: An apparatus for providing enhanced radar video processing may include a processing element. The processing element may be configured to receive, from a state table that is oriented in a fixed orientation, data based on a radar return, to store a texture corresponding to an image based on the received data, the texture being oriented with respect to a center of a radar sweep, to define a plurality of adjacent vertex buffers, and to map the texture to at least one of the vertex buffers in which portions of the texture are capable of being scrambled within at least one of the vertex buffers.

Abstract: Boundaries of a moving haven along a voyage plan are constructed with the utilization of simple shapes, rectangles and arcs, each of which are drawn with selected line segments. A buffer, internal to the moving haven boundary, is created, which, when crossed initiates a warning that the boundary of the moving haven is being approached. Procedures for the implementation of the moving haven boundary and the buffer are substantially similar, with but few modification from the procedure that generates the moving haven needed to establish the procedure to implement the procedure that generates the buffer.
