TL;DR: In this paper, a high-precision testing method for infrared emittance is presented, in which a standard reference black body is accurately moved to be within a view field range of a radiometer to be measured, avoiding that ambient environment temperature changes and stray light have bad influences on testing results, and the precision of testing is improved; the mechanical device is a mechanical arm capable of conducting accurate positioning on automatic control.

TL;DR: In this article, a novel outdoor-field static RCS prepositioned linkage calibration testing method is proposed, where the calibration calibrator is placed in front of a target calibrator, and the echo power of the calibrated calibrator and the echopower of the target calibrators are respectively measured.

TL;DR: In this article, a double-area temperature control large-caliber high-temperature infrared surface source blackbody device is described, which consists of a radiating surface, a central heating body, an outer ring heating body and a double PID type temperature controller.

TL;DR: In this paper, a near field test system fault analysis method based on an analytic hierarchy process relates to the field of fault analysis, where a target layer, a criterion layer and a scheme layer of a hierarchical structure model are established, the criterion layer comprises daily maintainability, safety, a fault occurrence rate, maintenance cost and a maintenance period, and the target layer is an upper system of a subsystem needing fault analysis in the scheme layer.
