Background
The radar electronic device mainly comprises a receiving system and a transmitting system. In the receiving system, the receiving extension integrates complex operations of receiving, converting, processing and the like of all signals of the radar, so that a large number of wires are arranged inside the receiving extension. At present, for the convenience of debugging and maintenance, a receiving extension is often composed of a signal excitation assembly, a frequency source assembly, a channel testing assembly, a down-conversion assembly, a digital intermediate frequency assembly and a power supply assembly according to different receiving functions; some receiving systems also integrate signal transmitting components, IFDSP signal processing components, redundant control components, and the like. The design scheme of the modular receiving extension classifies the functions of the whole receiving system, and greatly simplifies debugging and maintenance work. However, this design introduces other problems: the integrated plug-in units have multi-path routing lines, usually at least have half-flexible cables not less than 40, the routing lines are exposed on the back of the extension, under the condition that an optimized arrangement interface is not provided, the attractiveness of the extension is greatly influenced by disordered wiring, and the complex routing lines cannot be arranged through manual wiring; in addition, the situation that the wiring cables are unordered due to the disordered interface can easily lead the cable to be connected in a wrong way in the later debugging and maintenance work of the extension set by workers. In a word, the method for disordered wiring on the back of the extension is not suitable for debugging and maintaining the whole radar.

s2, carrying out infinite arrangement on elements in the equal-dimension vectors corresponding to each panel to obtain possible arrangement conditions of all plug-in interfaces, and forming a combination matrix formed by all the equal-dimension vectors;

and S4, performing superposition and summation on the assignments of all the combination matrixes to obtain the minimum assignment and the corresponding combination matrixes thereof, if the minimum assignment corresponds to a plurality of combination matrixes, assigning a pair of plugin interfaces to be the combination matrix with the most 0, if the pair of plugin interfaces has a plurality of combination matrixes with the most 0, assigning a pair of plugin interfaces to be the combination matrix with the most 1, and so on, wherein the finally obtained combination matrix is the arrangement mode corresponding to the plugin interfaces of the receiving extension.
Preferably, in S1, the plug-in interfaces on each panel are arranged into equal-dimension vertical vectors.
