    2. Lattice pop.1, characterized in that from phase-. rotator contains a 180-degree phasing section having first and second reflective diodes, and the controlled microwave power switch is designed as a two-position switch, the outputs of which are connected to the anodes of these diodes, the invention relates to radio engineering and can be used in devices that prevent decrease in the accuracy of installation of the antenna beam when the phase shifters are in good order; the phased antenna array is known, which contains the antenna element of the microwave power distribution circuit, which includes phases However, the C 12 switch is known to have a phased array antenna, which is characterized by an unacceptable error if the beam is installed when at least one phase shifter is out of service. The purpose of the invention is to increase the efficiency at the exit from the phase rotation, in particular, to increase the beam installation. To achieve this goal, a well-known phased antenna array containing antenna elements of the SBSh power distribution unit, including phase shifters, phase failure detection units and controllable microwave power switches connected in series with each of the phasers and connected to the control outputs of the mentioned units fault detection. Each of the phase shifters contains a 180-degree phasing section having first and second reflective diodes, and the controlled microwave power switch is made as a two-position switch, the outputs of which are connected to the anodes of the diodes that are used to control the bias voltage. Each of the phase shifters is provided with an input and output transmission line.
    with control inputs for supplying bias voltage.
    3. Lattice pop 1, characterized in that each of the phase shifters is provided with input and output transmission lines, and the controlled microwave power switch comprises a diode connected in series to one of said transmission lines. and the controlled microwave power switch comprises a diode connected in series to one of said transmission lines. Figure 1 shows the structural electrical circuit of the proposed phased antenna array; PA fig.2to same, the microwave power distribution unit, fig.Z - the same, 180-degree phasing section; 4 is the same, controlled by a microwave power switch. The phased array grating comprises antenna elements 1, a microwave power distribution unit including phase shifters 2, phase shifter fault detection blocks 3, controlled microwave power switches 4, each of phase shifters 2 containing a 180-degree phasing section consisting of the first and second reflective diodes 5 and 6, while the controlled switch 4 microwave power can be made in the form of a two-position switch, the outputs of which are connected to the anodes of the first reflective diode 5 and the second reflective About diode 6. In another embodiment, each of the phase shifters 2 is equipped with input and output transmission lines 7 and 8, and the controlled microwave power switch 4 contains a diode 9 connected in series to one of these transmission lines 7 or 8. In addition, phase shifter 2 has a coupler 10. The phased array array operates as follows. If one of the phase shifters 2 fails, the corresponding antenna element 1 is given a signal in an arbitrary phase, which leads to Po310918
    error in the angular position of the antenna beam. To prevent this, it is necessary to stop the signals to this antenna element 1. The malfunction detection unit 3 about-j detects the faulty phase shifter 2 by the correct voltage and bias currents of the reflective diodes 5 and 6. These voltages and currents have incorrect values The reflectors of diodes 5 and 6 are built in. The fault detection unit 3 usually operates during the periods when the antenna is not transmitting and checks the response of the phase to (5 of the rotator 2 to the phase control simulation signals. Output The only fault signal that indicates the failure of the elements of the phase shifter 2 is the output signal of the fault detection unit 3. This output signal can be sent to the operator console, providing a visual indication of the failure, as well as to the controlled microwave power switch 4, which, having received 25 the signal opens the input transmission line 7 to the faulty phase shifter 2, so that the microwave signals arriving at its input do not pass to the output.
    The controlled microwave power switch 4 is a relatively simple diode switch, in which a diode 9 is connected between the input 7 or output 8 transmission lines and the ground. 5 Direct bias on diode 9 causes the signals to ground to close. When diode 9 is supplied with voltage reverse
    14
    polarity, microwave signals can pass through input 7 or output 8 transmission lines.
    As a controlled microwave power switch 4, a 180-degree section of a multi-section phase shifter may be used.
    When the signal passes through the healthy phase shifter 2, the reflective diodes 5 and 6 are in a non-conducting state and the microwave signals fed to the input transmission line 7 are reflected from grounded circuits and transmitted to the output transmission line 8. If the offset on the reflective diodes 5 and 6 straight, they become flat wire and serve to ground the signals at a point that is located a quarter of the wavelength closer to the tap 10.
    Thus, the microwave signals travel from the input transmission line 7 to the output transmission line 8, a distance less than half the wavelength, and therefore acquire a phase shift of 180
    When control signals of different polarity are fed to the reflective diodes 5 and 6, the reflection coefficient on the input transmission line 7 becomes greater, which leads to the absence of a signal on the output transmission line 8. Thus, the application of the proposed phased antenna array with the power phase malfunction detection blocks considerably distributes it efficiency at failure of phase shifters, in particular, increases the accuracy of the beam installation.
