Abstract
A sonar simulation system comprises a general purpose digital computer andn interface processor which receives position and intensity information from the computer for the effects to be simulated and spreads the effects in range and bearing to simulate a PPI display. Simulated range-bearing cells are displayed on the PPI with a resolution of 0.5° making the time between cells 46 microseconds. During each 46 microseconds interval, all of the sonar effects are independently and successively examined to determine if they have a contribution to the next cell to be displayed. The intensity of each of the contributors are summed for output to the sonar interface equipment.
