The purpose is to realize the wide - band , high - speed , low - phase - noise and low - cost frequency synthesis in l band
The main work in this dissertation is as follows : 1 . have presented a scheme of l band wide band digital t / r module
The results show that the radius of the slow - wave structure can be much smaller in the coaxial bwo case than in the non - coaxial bwo case
Now there are many reports on bwos that operate in the frequency regime of x - band ( 8ghz - 12ghz ) or c - band ( 4ghz - 6ghz ) , but reports on l - band ( 1 . 12ghz - 1 . 70ghz ) are rare
The ultranet wave multiplexer concentrates up to 16 input channels on either a single fiber optic strand or a fiber optic cable pair . each input channel is capable of data rates up to 2 . 5
Secondly , based on the theoretical investigations , a coaxial bwo is designed which operates in the frequency regime of l - band . and its interaction process is analyzed
Moreover , the scheme of mmw optically controlled phased array radar is presented also . at last , the matching - circuit and apd receiver circuit are designed . the curves of the system are shown respectively
用l波段造句挺难的，這是一个万能造句的方法
In the non - coaxial bwo of l - band , the radius of the slow - wave structure is very large , and the volume and weight of the guiding - magnetic system are also very large . thus , the non - coaxial bwo of l - band is bulky and lumbersome and is inconvenient for real application
And then the theoretical performances of these algorithms are analyzed . finally , these algorithms are applied in l - band polarimetric data obtained by sir - c system . the calibration results of every algorithms and the comparison of these results are given in the paper
The relative development mature ( uses the l wave band ) face the digital audio frequency service satellite numeral audio frequency broadcast technology beginning , because designs aims at the mobile subscriber , has solved the mobile subscriber receive numeral audio frequency broadcast problem well
Studies show that the radius of the coaxial l - band bwo can be smaller than that of the non - coaxial l - band bwo . the coaxial bwo of l - band can be very compact and convenient for real application . so investigation on the compact coaxial l - band bwo is of great interest to the high - power microwave field
Meanwhile a valuable conclusion that general cylindrical box type windows with dielectric disks made of al2o3 ceramic can be used to transmit cw of higher power than 120kw and workable relative bandwidth may achieve about 14 % in l band , is made by calculated results of some typical examples
In chapter 2 , first give the theory of phased array radar . second introduce the analog t / r module and digital t / r module . third discusses some key technology of wide band digital t / r module , including ddws technology and quadrature modulate technology . at last present a scheme of l bandwide banddigital t / r module
By utilizing hi - bi fiber loop mirror and fiber polarizer to control the intracavity polarization state , a multi - wavelength erbium - doped fiber laser by exploiting phb ( polarization hole - burning ) is realized . we have experimentally achieved four - wavelength or five - wavelength stable lasers with wavelength spacing of less than 2nm
Then , detail discusses were given on . finally , on the basis of above analysis and research , by comparing various design methods , a l band agile frequency synthesizer with 256mhz bandwidth and 1mhz resolution was designed , whose switching time was within 4 us . however , the spur performance is to be improved
The third , some groping researches are made on broadband coaxial line filter output circuit of klystron . a broadband output circuit - mode four coupling slots double - gap output cavity loaded with coaxial filter , which has a workable relative bandwidth bigger than 14 % and fits in with l - band multi - beam klystron , is designed . meanwhile some analysis of its stability and peak power capacity is made
It is a quite complicated system and involves many fields : accelerator physics , microwave electronics , vacuum physics , low temperature physics and etc . based on this facility , there are some physics issues " analysis and numeric simulation on the accelerator in this dissertation
