Embodiment 1

[0037] like figure 1 , the method for comprehensive performance evaluation of adaptive zeroing antenna includes the following steps:

[0038] (1) Establishing an evaluation hierarchy model

[0039] by figure 2 shown in the example. The hierarchical structure model is divided into the target layer, the middle layer and the bottom layer. The target layer is the evaluation target, that is, the performance evaluation of the adaptive nulling antenna system. The middle layer can be divided into several sub-layers, and in this embodiment, it is specifically divided into a criterion layer and an indicator layer below the criterion layer. The elements of the criterion layer are various criteria, such as the anti-jamming effect criterion and the anti-jamming cost criterion shown in the figure. The elements of the indicator layer are various indicators under each criterion. For example, there are three indicators under the anti-jamming effect criterion shown in the figure: zero dep...

Abstract

The invention discloses a comprehensive effectiveness assessment method of an adaptive null-steering antenna. The method comprises the following steps: firstly, building an evaluation hierarchy structure model, and calculating evaluation scores of the adaptive null-steering antenna under different conditions by using an analytic hierarchy process, so as to carry out comprehensive assessment of the effectiveness on the adaptive null-steering antenna. By adopting the comprehensive effectiveness assessment method, the technical problem of comprehensive assessment based on each index of the adaptive null-steering antenna can be solved, the comprehensive effectiveness assessment method can be widely applied to the fields of radar, communication and the like, which employ the adaptive nulling antenna system, and technical research, production and improvement of the adaptive null-steering antenna system can be guided.

Description

technical field [0001] The invention relates to the fields of self-adaptive zero-adjustment antennas and performance evaluation, in particular to a method for comprehensive performance evaluation of self-adaptive zero-adjustment antennas based on analytic hierarchy process. Background technique [0002] Adaptive nulling antenna technology is a spatial filtering technology based on array antennas, which is widely used in radar, communication, medical imaging, and microphone voice processing. This technology uses different kinds of adaptive algorithms to adjust the amplitude and phase weighting of each antenna element, so that the pattern of the array antenna reaches the maximum value in the direction of the desired signal, and forms a null in the interference direction, so as to achieve the maximum in the airspace. The purpose of receiving useful signals while suppressing interference. The comprehensive performance evaluation of adaptive nulling antenna can not only be used ...
