Abstract. The design of a number of
millimeter-wave quasioptical radio-wave transceiving devices for the
millimeter-wave and near-infrared bands is considered, and the results of their
testing are presented. Some applications of these devices are presented for
solving radiophysical problems. It is shown that, on the basis of a simple
quasioptical transceiving device, one can design a whole series of
radio-engineering devices: devices for monitoring transmitted power, for
measuring reflections, and for measuring a depolarized component of the field.
By splitting a quasioptical beam into several identical channels, one can
design a multichannel device and even a matrix of such channels. The solution
of polarization problems requires an equipment that can simultaneously receive
orthogonally polarized components of the reflected signal. In the paper, a
variant of a bipolarization unit is described that can simultaneously receive
two orthogonally polarized components of the reflected signal. It is shown that
multichannel introscopes operating on the depolarized component can be designed
that allow the detection of hidden metallic, as well as dielectric objects.
Keywords: quasioptical radio-wave
transceiving devices, millimeter and near-infrared bands, multichannel devices.
