Paper Abstract

We have used the microwave radiometer to detect the early deep tumor such as esophageal nasopharyngeal and hepatical cancer . The control system of the microwave radiometer was designed by the analog control technique . This paper proposes a digital control system as a substitute for the earlier analog control system . The construction of the digital system in a microwave radiometer is ifiustrated and the features of the digital system are discussed. Compared with the analog control system the digital system based on computer software has distinct advantages in terms of : performance flexibifity interface etc.
