  • Circuit arrangement for calculating a visual distance in a digitally stored ground model
    Patent number: 4755959
    Abstract: A circuit arrangement for calculating a visual line of sight distance in digitally stored model. A distance long the line of sight is calculated by stepping radially outward along the line of sight. The step sizes which are chosen are selected based on the angle of the line of sight to the grid of the stored model and are selected to ensure that the evaluation points are at points of the grid. The stepping along the line of sight is performed by two sets of integrators and the output of one of the two sets of integrators is selected.
