Claim:
1. A method for testing a radio frequency index of an active antenna system, which adopts a testing cover to test the radio frequency index of a tested active antenna system, the method comprising: a testing cover monomer calibration, performing a cable loss calibration to a radio frequency line of each antenna of the testing cover through a vector network analyzer; a testing cover environment calibration, putting an antenna part in the testing cover after the monomer calibration, and fixing a spatial relationship between the antenna part and a test probe, and calibrating for a near field coupling environment between each dipole of the antenna part and the testing cover through moving the test probe; wherein, an dipole structure and composition mode of the antenna part are same as an antenna feeder part of the tested active antenna system, and the test probe is a standard antenna dipole; and a radio frequency index test, putting the tested active antenna system into the testing cover after an environment calibration, and fixing a spatial relationship between a dipole corresponding to the tested active antenna system and the test probe, wherein the test environment thereof is the same as a test environment after the testing cover environment calibration, performing radio frequency test on the tested active antenna system through a radio frequency port of the test probe after compensating the test environment according to a calibration result obtained from the calibration, and obtaining the radio frequency index of the radio frequency port of the tested active antenna system.
