摘要：
This paper presents several photonic architectures for independently steering multiple broadband nulls for linear and conformal phased away antennas. Analytic expressions that quantify bandwidth requirements are developed and both experimental and simulation results which demonstrate the antenna system performance are presented. In a fully integrated, optimized system, null depths in excess of 50 dB across a multigigahertz bandwidth are anticipated and the critical factors that influence this performance are examined.
