FIELD: physics.
SUBSTANCE: multichannel module of active phased antenna array for a radar station has a microcontroller and a set of transceiving modules, each consisting of an input and an output microwave communication element, a control circuit, a receiving channel and a transmitting channel, connected to corresponding control outputs of the control circuit, the control circuit of each transceiving module has series-connected buffered repeater, combined register and coincidence circuit, where the combined register consists of a shift and a parallel part, the clock input, data input and output of the shift part are, respectively, the shift input and serial input and output of the combined register, the output of each bit of the shift part is connected to the input of the corresponding bit of the parallel part, its gating input is the load input of the combined register, the multibit outputs of which are the control outputs of the control circuit, and the single-bit output is connected to the second input of the coincidence circuit, the output of which is connected to the control input of the pulse modulator of the transmitting channel, the combined registers of the transceiving modules are connected into a series circuit through their serial inputs and outputs, and the serial inputs and outputs of the combined registers of the first and last transceiving modules are respectively connected to the data output and input of the microcontroller, the buffered repeaters of the transceiving modules are connected into a circuit such that the input of the buffered repeater of the last transceiving module is connected to the clock output of the microcontroller, and the input of the buffered repeater of each previous transceiving module is connected to the output of the buffered repeater of the next transceiving module, the output of the buffered repeater of each transceiving module is connected to the shift input of the combined register of the given transceiving module, and the device also includes two buffer gates, the output of the first of which is connected to parallel write inputs of the combined registers, and the output of the second is connected to the second inputs of the coincidence circuits of each transceiving module, inputs of the buffer gates are clock inputs of the device.
EFFECT: easy routing of control signals and cutting the number of microcontrollers.
