Abstract:
This final report summarizes the progress during the Phase I SBIR project entitled "Embedded Electro-Optic Sensor Network for the On-Site Calibration and Real-Time Performance Monitoring of Large-Scale Phased Arrays". The main objective of the project is to develop an innovative electric-field sensor network based on an electro-optic field-detection technique (the Electro-optic Sensor Network, or ESN) for the performance evaluation of phased-antenna arrays at the end of their development/production cycle, and furthermore, for onsite test and calibration of deployed large-scale phased arrays. During the Phase I period, Opteos has built a small-scale ESN system for the feasibility demonstration. In the small-scale ESN system, three EO sensors were used. Opteos has also developed modified serial port to directly control the optical switch along with necessary software in order to acquire measurement data from the three EO sensors while the sensors scan over an antenna under test. The performance of small scale ESN was characterized by mapping two-dimensional field maps on a patch antenna. During the evaluation process, non-uniform channel-to-channel performance of the optical switch has been observed. In order to compensate the non-uniformity, a polarization compensation method has been developed.
