The objective of this project is to develop a band S radar-transmitter and integrate it to the Doppler Meteorological Radar System under development in Omnisys and to propose a modernization solution for all the obsolete radar systems currently installed. The classic radar-transmitter consists of four fundamental modules: the synchronous generator, the power supply, the pulse modulator and the high frequency emission element. Classic modulators use a delay line as an element for storing energy. Although reliable, they only have a single pulse length per delay line, as opposed to the need, in many applications, for this parameter to be easily adjustable. The modern solution for this deficiency was to develop a radar-transmitter entirely in solid state. Transmitters of this kind are, however, extremely expensive when compared to the classic ones and hardly viable for civil applications, especially for the market in focus. Therefore, the intention is to explore the low cost and high reliability of the magnetron-type emitter, developing a commutation circuit which does away with the use of delay line and enables easier regulation of the length of radar pulse.
