Miniature microwave radiometer for noninvasively detecting temperature abnormity in internal tissues

The utility model relates to the field of medical and medical equipment, in particular to a radiation temperature measuring method for noninvasively detecting temperature abnormity of internal tissuesof a living body by measuring inherent electromagnetic radiation intensity, and more particularly relates to a microwave radiometer for measuring the temperature of the internal tissues of a patientin a daily activity process. The device can be used as a part of a set of diagnostic measures for early identification of tumor diseases to detect temperature change and thermal abnormality of internal tissues of organisms. The microwave radiometer comprises the following elements connected in series: an application type antenna for contacting a living body, a switch, a circulator, a microwave signal amplitude detection and amplification device, a programmable analog integrated circuit, a Peltier amplifier and a Peltier element. Furthermore, a first matching load mounted on and in thermal contact with the Peltier eleme
