Abstract :
This paper deals with the analysis of technical capabilities of multichannel MMW radiometric sensors creation. The main aim of the given paper is the development of constructing principles of multichannel MMW RM receivers with a channelizing. The analysis is made for increasing interferences level and as a consequence to each channel sensitivity reducing in RM sensors. The realization of multichannel RM receiver under direct-detection receiver reduces the cost of the RM sensor.
