Paper Abstract

There exist the problems sending us in search of a simple,small in size and precision instrument to measure the parameters ofthe electromagnetic sygnal reflected from the object underinvestigation in the millimeter and submillimeter waves bands. Sucha problem can be cracked by devising an apparatus operating as atransmitter and a receiver simultaneously. Such a transmitter- receiver system is called autodyne and allows to do away with aheterodyne, a mixer, a receiving aerial, and waveguide commutators.The autodyne sensitivity depends on the level of the oscillatorinherent noise and the frequency instability. Therefore autodynesdevised on the base of BWT, magnetrons and klystrons give a bad fitfor microwave spectroscopy.
