Problems solved by technology

[0002] With the development of modern communication, the application of adaptive anti-jamming antenna is more and more extensive. Among them, when it is applied in the integrated channel system, a certain adaptive algorithm is often used to complete the adaptive process of the antenna. For example, the commonly used adaptive algorithm is Least Mean Square Algorithm (LMS Algorithm) and Least Square Algorithm (LS Algorithm), etc., however, the optimal use conditions of these adaptive algorithms are different. The problem that the performance is not high enough and the anti-interference ability is not strong enough

Embodiment 1

[0039] see figure 1 , figure 1 It is a schematic flowchart of a test method for an adaptive anti-jamming antenna channel integration system disclosed in an embodiment of the present invention. Such as figure 1 Shown, the test method of this adaptive anti-jamming antenna channel integrated system can comprise the following steps:

[0040]101. The control machine detects whether the change trend of the anti-jamming performance index of the antenna is decreasing, if yes, execute step 102, and if not, end this procedure.

[0041] In the embodiment of the present invention, the anti-interference performance index includes a front-to-back ratio, and a change trend is an increase or a decrease. Among them, the front-to-back ratio of the directional antenna refers to the ratio of the power flux density in the maximum radiation direction of the main lobe (specified as 0°) to the maximum power flux density near the opposite direction (specified within the range of 180°±20°). The lar...

Abstract

A test method and system for an adaptive anti-interference antenna channel integration system, comprising: a control machine detects the change trend and change amount of the anti-jamming performance index of the antenna, and when the anti-jamming performance index of the antenna becomes smaller and the change amount is greater than the preset change When the amount is measured, the control machine sends a switching command to the adaptive anti-jamming antenna channel integration system, and the adaptive anti-jamming antenna channel integration system switches the adaptive algorithm. By implementing the embodiment of the present invention, it is possible to use the control machine to automatically test the anti-jamming performance index in the adaptive anti-jamming antenna channel integrated system, adjust the adaptive algorithm according to the anti-jamming performance index, and adopt a better adaptive algorithm, thereby improving the system performance. reliability and enhanced anti-interference ability.
