Abstract

The invention relates to an anti-GPS interference system, and discloses an anti-GPS interference test system, for solving the problem of low test precision of a conventional anti-GPS interference test. In the system, a first antenna is used for receiving an interference signal output by a first jammer; a second antenna is used for receiving an interference signal output by a second jammer; a third antenna is used for receiving an interference signal output by a third jammer; the tail end of a self-adaptive zeroing antenna is connected with the first input end of a frequency spectrum analyzer; the tail end of the first antenna is connected with the second input end of the frequency spectrum analyzer; the self-adaptive zeroing antenna is arranged at the center of a test area; the second antenna and the third antenna are both arranged at one side of the self-adaptive zeroing antenna and are each taken as a low-elevation angle interference device; and the first antenna is arranged in the test area and is taken as an interference test device. The anti-GPS interference test system is applied to an anti-GPS interference test.

Description

technical field [0001] The invention relates to an anti-GPS interference system. Background technique [0002] At present, in the anti-GPS interference test, no matter in the single-interference environment or the three-interference environment, the test anti-GPS interference ability is poor, and the test accuracy is low. Contents of the invention [0003] The invention aims to solve the problem of low test accuracy of the current anti-GPS interference test, thereby providing an anti-GPS interference system. [0004] Anti-GPS jamming test system, which includes No. 1 jammer 1, No. 2 jammer 2, No. 3 jammer 3, No. 1 antenna 4, No. 2 antenna 5, No. 3 antenna 6, adaptive withering antenna 7 and spectrum analyzer 8; [0005] The first antenna 4 is used to receive the interference signal output by the first jammer 1; the second antenna 5 is used to receive the interference signal output by the second jammer 2; the third antenna 6 is used to receive the interference signal out...
