AB  - In this paper, a total radiometry array system that measures the heat source in the invisible area was designed using LNBF(Low Noise Block Feedhorn), a commercial satellite broadcasting reception equipment, and its effectiveness was verified through measurement and simulation results. Based on the Planck blackbody radiation theory that all heat sources emit electromagnetic waves, Ku-Band's electromagnetic wave energy was received in an LNBF array for commercial satellite broadcasting and the received power of the heat source was detected using a power sensor. When the heat source detection frequency band is infrared, the heat source detection performance is deteriorated in an environment with many obstacles, so the microwave band is more suitable in the case of invisible areas. In addition, the invisible heat source distribution was imaged through movement detection by mounting an LNBF array on the XY-plotter. In this study, it consisted of a large number of cement resistance and hot water as heat sources and the heat sources were wrapped with a tinting film for heat blocking for the invisible environment. The results of this study are expected to be used to detect invisible heat sources generated during power short circuits and short circuits inside buildings.
