A radar test set for the super-high-frequency band of 9000-9700 Mc/s

The paper describes a radar test set for the frequency band of 9 000¿9 700 Mc/s. Details are given of the waveguide system and of the electronic circuits of the set. The measurements which are required in order to check and service the transmitter, receiver and associated parts of a radar set are set out, and the method of making the various measurements with the test set are outlined.
