FIELD: radio engineering, communication.SUBSTANCE: invention relates to radio-measurement techniques. The asynchronous panoramic radio receiver includes series-connected antenna, input circuit, high frequency amplifier, first asynchronous detector, first video amplifier, differentiating circuit and vertical deflection plates of a first oscilloscope, the horizontal deflection plates of which are connected to the output of a frequency sweep generating unit, connected in series to the output of a heterodyne - 90° phase changer, second asynchronous detector, the second input of which is connected to the output of the high frequency amplifier, second video amplifier and horizontal deflecting plates of a second oscilloscope, connected in series to the output of the differentiating circuit - pulse former, first switch, the second input of which is connected to the output of the first video amplifier, and vertical deflection plates of the second oscilloscope, wherein control inputs of the input circuit, high frequency amplifier, heterodyne and frequency sweep generating unit are connected to corresponding outputs of a control unit. The device is equipped with two squaring devices, an adder, a square-root extracting unit, a divider, an arctangent determining unit, a second switch, a frequency metre and a recording and analysis unit. The output of the first switch is connected in series to the first squaring device, the adder, the second input of which is connected through the second squaring device to the output of the second video amplifier, the square-root extracting unit and the recording and analysis unit. The output of the first video amplifier is connected in series to the divider and the arctangent determining unit, the output of which is connected to the second input of the recording and analysis unit. The output of the heterodyne is connected in series to the second switch, the second input of which is connected to the output of the pulse former, and the frequency metre, the output of which is connected to the third input of the recording and analysis unit.EFFECT: broader functional capabilities.4 dwg |
