- W4328107773 abstract "This paper describes the development of a wide-band active array system with a photonics-based optical transceiver module (OTM) and measurement results of Tx/Rx beam characteristics using near-field measurements. The proposed transceiver consists of an RF transceiver module and an OTM. The RF transceiver module was designed as a 2×8 array using a microstrip dipole antenna. The OTM performs frequency up/down conversion using an optical modulator and has four Rx channels of A/B/C/D for mono-pulse angle extraction. The transmit and receive modules include a true-time delay to electronically steer the wide-band beam over an azimuth angle of ± 20°. The Tx/Rx beam pattern is measured at a near-field measurement facility. The beam steering error is less than 0.9° over the ±20° azimuth angle in the wide Ku-band. In addition, the monopulse slope is obtained from the Rx 4 optic array, and the function of the monopulse calibration is verified using outdoor measurements." @default.
