Meters for Exciting Current of Emitters in Transmitting Short-Wave Band Phased-Array

In ring PAL SW of a range there are the strong fields of interacting leading to change of impedances of emitters. Any change of state ring PAL influences values of currents in them. Therefore with a view of maintenance of functioning ring PAL the circuit design of the multichannel measuring has been developed. In such system the most important device is the multichannel metre of amplitude and a phase of the current leaking on each element ring PAL.

Estimation of complex value of entrance resistance of an emitter, and, hence, and a current in it, it is possible to gain on values of voltage of the dropping and reflected waves. In the capacity of such sensing transducers bridge measuring of entrance resistance or sensing transducers of the dropping and reflected waves find application. First from them serve for preliminary adjustment of the matching device and function at small level of a signal. Therefore in the basic section of a food in the capacity of the sensing transducer it is possible to apply to turning on only sensing transducer DRW from which exit it is gained complex values of voltage of the dropping and reflected waves.

Signals removed from sensing transducers are processed the microcomputer on the algorithm developed and presented in paper. Application of the given measuring allows not only to make the control ring PAL in a regular regime of functioning, but also to carry out restoration OD by regulating of amplitudes and phases of the currents energising its elements.
