FIELD: radio engineering. ^ SUBSTANCE: transmitting system consists of a transmitter and an antenna. Modulating signal generator is connected to transmitter. Sustained from antenna of transmitting system are measuring antenna and screened cabin. Aforementioned cabin contains first switch, one input of which is connected to measuring antenna, and another input - to calibrating generator, while output is connected to input of second switch. First output of the latter is connected to input of a system of filters. Cabin additionally contains third switch, attenuator and measuring receiver. Inputs of fourth switch are connected to output of transmitter and auxiliary source, while output is connected to antenna of transmitting system. Connected serially are rejecter filter, input of which is connected to first output of third switch, and band filter, output of which is connected to input of attenuator. One input of registration device is connected to signal output of measuring receiver, another one is connected to its frequency output through frequency meter. First four outputs of multi-channel control block are connected to control inputs of switch of appropriate number, fifth and sixth inputs - to rotation mechanisms in level plane of transmitting system antenna and measuring antenna; seventh, eighth, and ninth, respectively, to hoisting mechanism and mechanisms for measuring inclination of measuring antenna in the plane of position angle and polarization. Second output of second switch is connected to input of third switch, output of system of filters and second output of third switch - to input of attenuator, output of which is connected to input of measuring receiver. ^ EFFECT: expanded measuring limits, increased precision and increased speed of operation. ^ 1 dwg |
