Abstract:

Over wide altitude ranges, signals representative of the altitude of an eyepoint viewing a synthetic grid pattern on a ground reference plane are scaled to provide strong signals. These strong signals are used to electronically define the intersection of a line of sight from the eyepoint to the grid pattern so that a clearly defined grid pattern as viewed over the wide altitude range can be displayed.
