【Abstract】 As the third generation radar, phased-array radar was widely used in the military and civil domain. Combined the engineering need, this paper discussed the common used device such as the ferrite phase shifter, power divider, direction-coupler and power equalizer, based all of this, analyzed and designed a ferrite phased shifter and feed line incorporate net . The main contents are as follows:1. The characteristic and developing direction of the phased-radar are investigated in detail, analyzed the technology characteristic of the different phase shifter used in the phased radar, and submitted the thereunder of this paper.2. The characteristic of the gyromagnetic ferrite are studied in detail, analyzed the waveguide which was inputted the transverse magnetization gyromagnetic ferrite. Discussed the reciprocal and un-reciprocal ferrite phase shifter, constructed the compute mode of the un- reciprocal ferrite phase shifter, and designed an X-band ferrite phase shifter by this.3. The common device used in the phased radar feed-out system such as waveguide power divider, coaxial power divider, wide-band direction coupler. For the power aberrance of the traveling-wave tube, analyzed and designed a power equalizer.4. Based on the study of the un- reciprocal ferrite phase shifter and feed out power divider, researched the technology of the ferrite phased shifter and feeder line incorporate net,included the principium of the incorporate net, the technology of the array cell amplitude distribution and the incorporate of the net, and discussed the antennas which were fit of this structure.5. Based on the research above , designed and factured this incorporate net, analyzed the test result in the last.更多还原
