Abstract:
This report documents the work accomplished during the Design Performance Verification II program. The scope of this program included the integration and evaluation of the 405B Advanced Development Program 1 Gbps digital baseband laser communication subsystem brassboard. It also included set up and checkout of the brassboard communication and the brassboard acquisition and tracking subsystems at the Air Force Avionics Laboratorys facility, and evaluation of static crossed field photomultipliers in the subsystem. The overall system performance for 0.000001 bit error rate BER was achieved with 52 pepulse for the brassboard communication subsystem. This was much better than the 80-100 pepulse achieved in the Design Performance Verfication I program and compares very favorably within 2 dB with the 35 pepulse baseline established in the Subsystem Preliminary Design Study AF contract F04701-71-C-0328. Several static crossed-field photomultipliers SCFP were evaluated during the course of the program. The subsystem performance with the SCFP was worse in every test relative to performance with the dynamic crossed field photomultiplier DCFP due probably to low rate noise spikes at the detector output and to the wider pulse widths of the SCFP which contribute to intersymbol interferences.
