ABSTRACT:
A sonar simulation system comprises a general purpose digital computer and n 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.degree. 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.
