Abstract
A new X-band meteorological radar transmitter developed recently is described in this paper. At first this paper conforms to the requirements of the Magnetron, in the course of nature work. This paper gives the technical indexes of the transmitter and its function profile for which to meet the requests of the transmitter, and also introduces the principle and function of every part in this profile. The new techniques used in this transmitter such as the Flyback charge, the solid modulator and the double line Pulse Format Net (PFN) are especially introduced. The solid state modulator design uses 3 SCRs in series as the discharge switch(solid state MOD); It is charged by the hige voltage power supply in forms of flyback charge; 1μs rectangle pulse is formed by double line PFN, specialy it gives the strict theory analyses, from here we get the reliable parameter for designing the MOD. The result proves that the logical analysis and parameters' selection are reasonable, which meets requests of practice.关键词
