Problems solved by technology
The disadvantage of the existing technology is that the calculation of the real-time position of the object under test based on the real-time phase difference requires a large amount of calculation, consumes a lot of system resources, and the calculation speed is slow, which does not meet the needs of real-time positioning.

Embodiment Construction
[0012] like figure 1 , the synchronous antenna array has eight antenna elements 1, 2, 3, 4, 5, 6, 7, 8, and there are nine theoretical positions A, B, C, D, E arranged in sequence along the one-dimensional direction on the ground , F, G, H, I.
[0013] Before locating the active DUT in real time, calculate the theoretical phase difference for different theoretical positions. Each theoretical phase difference is specifically the same theoretical position signal sent by the DUT at each theoretical position in each antenna element the phase difference between. Taking the object under test at the theoretical position A as an example, the same position signal sent by the object under test is received by each antenna element. Because there is a small difference in the distance from the theoretical position A to each antenna element, the phase of the same position signal is not the same when received by each antenna element, so the same position signal has a phase difference betwee...

The invention relates to a method for positioning an active to-be-measured-object in real time by using synchronous antenna arrays, and the method is completed in a way that a functional module framework is established, a computer system is controlled by computer program instructions, the method specifically relates to that the real-time position of the to-be-measured-object can be obtained according to real-time phase difference of a same real-time position signal (among the antenna array elements) sent by the active to-be-measured-object in real time. According to the method, a plurality of pre-stored theoretic phase differences which respectively represent different theoretic positions are taken out; specially, each theoretic phase difference is the phase difference of a same theoretic position signal (among the antenna array elements) sent by the to-be-measured-object at each theoretic position; the theoretic phase difference which is closest to the real-time phase difference is determined and the theoretic position represented by the closest theoretic phase difference is taken as the real-time position of the to-be-measured-object, so that relatively correct real-time positioning of the active to-be-measured-object can be realized via relatively small calculation.
Description
technical field [0001] The present invention relates to a method for using a synchronous antenna array to locate an active object to be measured in real time, and specifically relates to obtaining the real-time phase difference between the antenna array elements of the same real-time position signal sent by the active object to be measured in real time. The real-time position of the measured object. The method is accomplished by establishing a functional module framework and controlling the computer system by computer program instructions. Background technique [0002] There is a technology for real-time positioning of active DUTs with synchronous antenna arrays. Each antenna element receives the same real-time position signal sent by the object to be measured in real time, and calculates the relative phase of the real-time position signal in each antenna element, so as to obtain the real-time phase difference of the real-time position signal between each antenna element ,...
