In this paper,a novel method of range ambiguity resolving based on hybrid filter is proposed for high-pulse repetition frequency (HPRF) *** considering the discrete-valued pulse interval number (PIN) which is described as the radial range of the target divided by the maximum unambiguous range for a certain HPRF and its incremental variable as target states,the problem of range ambiguity resolving is converted to the hybrid state estimation *** the initial time steps,since the range measurement is ambiguous,the hybrid state initialization is achieved by utilizing multiple HPRFs based on Euclidean ***,to avoid the choice of the thresholds,the hybrid model based on six-dimension state vector is made equivalent to several hybrid models based on five-dimension state vector according to the values that PIN incremental variable may *** hybrid estimation is achieved by comparing 2-norm of the innovations obtained from several hybrid *** results demonstrate that the proposed method can converge more rapidly than the existing multiple hypothesis method when only one HPRF has target measurement and overcome the mistake that multiple hypothesis method makes when PIN varies.

XML is the standard format for data exchange between inter-enterprise applications on the Internet. To facilitate data exchange, industry groups define public document type that specify the format of the XML data to be exchanged between their applications. In this paper, we propose a new method to solve the problem of automating the conversion of relational data into XML. During the conversion, we considers not only the structure of relational schemas, but also semantic constraints such as inclusion dependencies during the translation--it takes as input a relational schema where multiple tables are interconnected through inclusion dependencies and converts it into an X-Schema. Finally, in order to validate our proposal, we present experimental results using real schemas.

To measure the frequency deviations of two frequency sources, we can examine the time difference. Cause the low precision of direct measurement can’t meet the high accuracy requirement. Dual-mixer time difference measurement can improve the measurement accuracy. This paper introduced the principle of Dual-mixer time difference measuring and contribution to frequency measurement of high accuracy and high frequency resolution;raised a new concept of triple samples variance used in measurement of Dual-mixer time difference;and gave suggestions in improving DMTD measuring capabilities.
