Abstract:

The holographic measurement on the 25 m parabolic antenna by the Sheshan station of Shanghai Observatory and the application of the measurement receiver in it are introduced.The basic theories of the microwave holographic measurement technique and the composition of the Sheshan station measurement system are described with emphasis on the principle of the composition of the measurement system and its application in Sheshan station.The measurement result with the SinoSat satellite beacon signal as a measurement signal is given.The measurement receiver is stable.

Key words: holographic measurement;measurement receiver;frequency division multiplexing
