Abstract:
A method of testing an antenna comprising the steps of:(a) radiating a test signal from a test signal source from a plurality of spaced apart signal source directions relative to a boresight of said antenna, and having respectively different orthogonal principle plane parameters relative to said boresight of said antenna, so that said test signal is incident upon said antenna from a plurality of different directions relative to the boresight axis of said antenna;(b) for each of the plurality of spaced apart signal source locations employed in step (a), receiving and demodulating signals received by said antenna;(c) correlating a replica of said test signal with signals received and demodulated in step (b), so as to extract energy in said test signal and exclude energy in any other signals that may be incident upon said antenna; and(d) processing test signal energy extracted in step (c) to derive a measure of said one or more characteristics of said antenna.
