A Diagnostic Subsystem for Array Transmit Antenna Control - Concept, Realization and Measurements

In the paper, a diagnostic subsystem to control radar antenna system parameters with transmit pulse power up to several hundreds KW is described. The proposed BITE subsystem is used to control power level at the input and all outputs of Transmit Beam Forming Network with 24 radiating structures. The subsystem controls the reflected power from antenna rows, as well. Antenna parameters are controlled at nominal power level in ON LINE mode of radar operation. Realization of diagnostic subsystem is presented in details. The results of measurements of Passive Antenna System obtained by BITE subsystem are shown.
