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.
