Continuous Computing Devices for Built-In Diagnostic System of Transmit/Receive Module in Active Phased Array Radar

摘要

Despite the high reliability of the APAR achieved through redundancy, failure and even deviation from the tolerances of the PPM parameters gradually leads to unacceptable changes in the radiation pattern of the APAR and, as a result, to a decrease in the accuracy of the radar with respect to the coordinates of the target. Periodic monitoring of the health of the elements by disabling the antenna and laborious monitoring of all emitters is necessary. There is a need to include automatic switching devices and coordination of the operating modes of the control devices and equipment for generating stimulating signals, state memory circuits controlled by the control devices, and control logic of connecting the control devices to control circuits as part of the control system. The paper discusses approaches to reducing the complexity, increasing the efficiency of the restoration of efficiency and the effectiveness of monitoring operational characteristics by integrating the integrated monitoring and diagnostics systems (IMDS) into the antenna structure.
