Abstract:

For the problem of evaluating countermeasure effectiveness against the adaptive nulling antenna, the evaluating method using the analytic hierarchy process (AHP) is proposed. First, evaluating indexes of countermeasure effectiveness are selected and the hierarchical structure model is established. Then, the method of evaluating countermeasure effectiveness is obtained by using the AHP. Finally, the performance indexes of three classical adaptive nulling algorithms are evaluated with various space jammings. The results of simulation show that the method can evaluate different countermeasure means reasonably and effectively, and it also has a strong adaptability. The research can be not only used in optimizing countermeasure means and their effectiveness evaluation, but also helpful for improving the anti-jamming technology of the adaptive nulling antenna.

Key words: adaptive nulling antenna, jamming effectiveness evaluation, analytic hierarchy process, mainlobe jamming
