Timing for Extended Target Simulation.
Abstract
Several timing runs were conducted on the CDC Cyber 73 system for the baseline extended target simulation program. The timing is dominated by the Doppler update in ETGDM, the subroutine that should also be called more frequently than ETGEO. If both subroutines are implemented on the Datacraft/6, one can anticipate about a factor of 3 slower performance. Thus about 4 scatterers can be accommodated. The glint and Doppler modulation (ETGDM) is best done on the AP120B. Assuming a conservative factor of 20 faster performance for this processor.
