Abstract:

In order to address the challenges posed by multiple test factors, a large sample space, and high overall test cost in radar anti-jamming testing, the constraint satisfaction method is introduced to analyze the characteristics of the radar anti-jamming test sample space and reduce its limited size. A framework for analyzing the sample space of radar anti-interference tests is proposed. The analysis of the sample space is translated from electromagnetic field to mathematical field, and a coupling constraint satisfaction model is established. The graph theory coupled constraint solving algorithm based on the twin variable method and the arc compatibility algorithm are combined to solve the coupling constraints in the test sample space. The results indicate that the reduced space is approximately 76 760.76 times more compact than the original test sample space, addressing the challenging issue of sample set selection in subsequent test design and offering support for radar anti-jamming test design and evaluation.

Key words: anti-interference test, sample space, coupling constraint satisfaction problem, twin variable method, arc consistent
