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. ...
