Simultaneous Phased-Array Element Testing Using Orthogonal Amplitude Modulation

2022 IEEE INTERNATIONAL SYMPOSIUM ON PHASED ARRAY SYSTEMS & TECHNOLOGY (PAST).

By: S. Almahmoud n, Z. Hong n  & B. Floyd n 

author keywords: Coded modulation; phased array; beamformer; built-in self-test; BIST; CoMET
TL;DR: The theory for AM-CoMET is presented and its operation using an eight-element phased array transmitter operating at 8 GHz is demonstrated, showing that AM- coMET extracted gain and phase are accurate to within 0.25 dB gain error and 2° phase error. (via Semantic Scholar)
