摘要:
AbstractThe carrier‐phased array—in which array phasing is derived from the incident modulated signal—is conceptually a very simple means of achieving automatic beam pointing in communications systems. The technique is particularly suitable for satellite reception applications, although careful consideration must be given in a practical design due to problems associated with the low signal levels derived from satellite broadcasts. In this paper, the basic principles of operation of such an array are described and the requirements of a practical system are addressed, resulting in the design and evaluation of an array system suitable for use with BPSK modulated signals from a communications sate
