  • Electronic unit, especially for detecting living organisms
    Patent number: 7636048
    Abstract: A unit having a transmitting antenna (3a) and a receiving antenna (3b) connected through a coupling block (3) to a reference oscillator (1) and to a recording oscillator (2), the reference oscillator (1) is connected to a converter f/U1 (4) for measuring and changing frequency of the reference oscillator (1) to a voltage necessary for feedback check of the reference frequency, and to an analogue block (7) for measuring variation of the reference oscillator voltage. The recording oscillator (2) is connected to a converter f/U2 (5) for measuring and changing frequency from the detecting oscillator (2) to a voltage necessary for checking the received frequency. Converter f/U1 (4), analogue block (7), detecting oscillator (2) and converter f/U2 (5) are connected to a digital block (6) for recording, controlling, surveillance and regulating the respective operations and evaluating operation of the respective blocks. The digital block (6) is connected to the reference oscillator (1).
