现代医学辐射计的特点和使用的天线类型被认为是。描述了生物对象的多层结构的各个层对所测量的亮度温度的贡献的方法。研制了一套微波辐射测量天线合理参数系统。本文提出了一种方法计算建模的三个不同尺寸的波导天线的设计参数，使用时域有限差分法（FDTD）。一组合理的参数已被开发，确认这些功能的性能，并提供优化天线设计的可能性时，设计多通道多频医疗辐射计。
The characteristics of modern medical radiometers and the types of antennas used in them are considered. The method of accounting for the contribution of individual layers of the multilayer structure of a biological object to the measured brightness temperature is described. A system of rational parameters of antennas used in microwave radiometry has been developed. The paper presents a method for computational modeling of the design parameters of three waveguide antennas of various sizes using the finite-difference time domain (FDTD) method. A set of rational parameters has been developed that confirm the performance of these functions and provide the possibility of optimizing the antenna design when designing multichannel multifrequency medical radiometers.
