An exemplary embodiment of the invention relates to a computer-based
program and system for displaying visually realistic raw radar signals.
The computer program includes a RADAR display fade algorithm. The
algorithm includes alpha blending and texture mapping for producing a
slow fade. Use of two buffers and transfer of data between the buffers to
produce a smooth update of the visual display while the sweep of the
RADAR ray advances and new or updated RADAR contacts are displayed.
