摘要：
This paper 1,2 presents the architecture and initial measured performance of an X-Band Digital Beamforming (DBF) Plug-and-Play Receive Array. This processor was designed to steer four independent simultaneous beams over the entire X-band with 32 independent channels, an instantaneous bandwidth of 15 MHz, and a spur-free dynamic range of at least 65 dB. Designed using commercial-off-the-shelf (COTS) components, we achieved a vast decrease in size of the DBF processor. When compared to previous DBF systems, the system's ease in mobility and measurement accuracy greatly increases DBF's applicability towards smaller airborne platforms.
