Abstract:
The present invention discloses a method for defining a metropolitan area based on a regional inter-city flow intensity measurement model. The method includes the following steps: 1. determining an urban agglomeration regional range to be measured and inter-city flow associated cities; 2. measuring, according to the determined associated cities, itemized regional inter-city flow intensities of each group of the associated cities, where five items, namely, economic flow, passenger flow, freight flow, technical flow, and information flow are included; 3. calculating through weighing, according to the five itemized regional inter-city flow intensity values, integrated inter-city flow intensities and membership degrees thereof between a central city and other associated cities; 4. recording the above data into an ArcGIS library, and establishing a regional inter-city flow database through association between spatial data and table data; 5. performing four groups of naturally intermittent type clustering analysis on data in the established regional inter-city flow database, and finally determining the range of a metropolitan area in a narrow sense and in a broad sense. By using the present invention, city linkage intensities can be measured quantitatively and comprehensively in a multi-factor mode, and accordingly the multi-circle range of a metropolitan area is defined.

Abstract:
The present disclosure provide a multi-beam chip integration module and a phased array system, wherein the multi-beam chip integration module comprises a first printing board, at least one set of first-type chips, and at least one set of second-type chips, the at least one set of first-type chips surface mounted to a first side of the first printing board, and the at least one set of second-type chips surface mounted to a second side of the first printing board, and wherein the second side of the first printing board is an opposite side parallel to the first side of the first printing board. Where the number and size (specification) of the first-type chips and the second-type chips do not change, surface mounting the first-type chips and the second-type chips to two sides of the first printing board requires a smaller area, i.e., a smaller size, of the first printing board as compared to surface mounting the same to one side of the first printing board. Therefore, the chip layout following the reduced size of the printed board can be satisfied, the wiring complexity of the antenna network can be reduced, and the chip layout can be completed in a simple and rapid manner.
