The ways of increasing the sensitivity of a non-selective thermal radiation receiver based on cadmium antimony using the phenomenon of electromagnetic induction are considered and investigated. It has been shown that the application of anisotropic NdFeB anisotropic magnet increases the volt-watt sensitivity of the thermal radiation receiver by 30 %. When a more powerful magnet is used, an additional increase in sensitivity is observed, but not in proportion to the magnitude of the additional magnetic induction. The dynamic range of the created thermal radiation receiver, which is from 10 to 200000 W/m-2, is investigated.
