MAtrix Radiometric System project ( MARS ). First phase MARS-1 . ... MARS-1 stage of the project main goal is to work out and then investigate single radiometric module of the assumed matrix system, taking into account the possibility to clone it for the next phase of the project. MARS-1 radiometric module is composed of the front-end amplifier ( LNA ) phase, main and back-end amplifier stages, band-limiting filter, detector and low-frequency preamplifier ( figure 1 ). Figure 1. ...
