FIELD: measurement technology, remote location of object, for instance, towed craft relative to tow-boat. SUBSTANCE: device for remote location of object includes measurement unit incorporating master generator, switch-former, power amplifier, switch, switched-over attenuator, first receiver and amplitude-phase meter connected in series. Output of master generator is connected to second input of first amplitude-phase meter. Outputs of switch-former are connected to controlling inputs of power amplifier, switched-over attenuator and switch connected to receiving- transmitting antenna. It also has repeater incorporating master generator, switch-former, power amplifier, switch, switched-over attenuator, receiver and amplitude-phase meter connected in series. Output of master generator is connected to second input of amplitude-phase meter, outputs of switch-former are connected to controlling inputs of power amplifier, switched-over attenuator and switch connected to receiving-transmitting antenna. Measurement unit of device is inserted with receiving antenna, second receiver, second amplitude- phase meter, direction computing unit, location computing unit, range computing unit, frequency synthesizer connected in series first and second outputs of synthesizer are connected correspondingly to second inputs of first and second receivers. First and second outputs of range computing unit are connected correspondingly to controlling inputs of switch-former and frequency synthesizer. Third output of range computing unit is connected to input of master generator which output is linked to second input of frequency synthesizer and second input of switch-former. Outputs of the latter are connected to inputs of first and second amplitude-phase meters. Output of first amplitude- phase meter is connected to input of range computing unit which output is connected to second input of location computing unit. Repeater is inserted with computer, frequency synthesizer and phase inverter connected in series. Output of phase inverter is connected to second input of power amplifier. Output of master generator is connected to input of switch-former and to second input of frequency synthesizer which second output is connected to second input of receiver. Proper output of switch-former is connected to controlling input of computer which second output is connected to controlling input of phase inverter. EFFECT: expanded functional capabilities and increased accuracy of remote location of objects. |
