Problems solved by technology

[0007] From the above analysis, it can be seen that whether it is a software time domain gate or a hardware time domain gate, the existing implementation methods are inseparable from the assistance of wired cables. For the standard test field, due to the specificity of the test site, the site environment does not exist. For other infrastructure such as buildings or roads, the wired cable connection method is applicable in the case of short sending and receiving distances. way is no longer possible
For the antenna test field that does not meet the requirements of the standard field, especially the test field on the high-rise buildings in the city, it is impossible to realize the cable connection method

Description

technical field [0001] The invention belongs to the technical field of antenna testing, and in particular relates to an antenna testing method and system based on wireless pulse technology. Background technique [0002] At present, the conventional mainstream antenna test system adopts the frequency domain test method to use the antenna under test to receive the excitation signal. The frequency domain test does not have the ability to distinguish time domain signals. will enter the receiver at the same time as figure 1 As shown, the useful signal 7 of the direct wave and the multipath interference signal 8 (the direct wave reflected by other targets such as buildings and brackets in the test environment) enter the receiver at the same time after being superimposed, and the receiver cannot identify and distinguish the signals 7 and 8. The actual receiving and processing signal of the test antenna will contain interference components, resulting in errors in the test results. ...
