As such diagnosing problems is very actual, process of EDS developing always on the first place, and each new expert diagnostic system should provide a full cycle of system diagnostic. The program system, allowing describes structure of the system diagnosability, organize data acquisition and it processing by the set algorithm is offered.

Step-by-step validation technique of constituent units of active phased antenna array at it sequential assembling is offered. The validation consists of electrical testing, electrical alignment and issue passports. In the beginning of everyone specifically-observed stage the checking of the final assembly units of the previous stage is provided. Note, the final assembly units of the previous stage are the component units of the specifically-observed stage unit, which should be tested. The mentioned checking of each final assembly unit of the previous stage is carried out in mode of in-phase and amplitude uniform excitation of its component units.

A design is suggested for testing equipment of antennas operating in short millimeter waveband (SMW). Testing is based on amplitude and phase measurements over a plane in the near field of the antenna under test. Design solutions are offered for critical subsystems, including the mechanical scanner, the radio-measurement subsystem and the automatic control subsystem. The approach should allow near-field testing of SMW antennas to achieve high accuracies comparable to those of similar testing of centimeter waveband antennas

Problems of design of Expert System of Diagnosis (ESD) are considered. It is suggested to develop an expert dynamic system of diagnosis for the control of the state of different hardware-in-the-loop complex suites for which the model of one of the possible ways of design of the latter is given.
