Abstract:

In order to solve the radio frequency (RF) stealth performance evaluation problem of aircraft swarm in air combat mode, an evaluation algorithm based on normal wiggly hesitant fuzzy set (NWHFS) is proposed. Firstly, a weight-determining model based on the best-worst method (BWM) with normal wiggly hesitant fuzzy information is constructed, the attribute weight vectors and consistency check coefficients are obtained. Secondly, based on the swarm's frequency equipment parameters and specific air combat scenarios, the RF stealth performance evaluation factors and their calculation formulas are obtained. And then, a evaluation matrix based on evaluation factor and its subjective experience is constructed and the attribute weight vector is used to aggregate the evaluation information. Finally, the NWHFS score function is used as evaluation index to quantitatively evaluate the RF stealth performance of aircraft swarm in different scenario. Simulation example and comparison analysis verify the feasibility and effectiveness of the proposed evaluation method.

Key words: air combat mode, aircraft swarm, normal wiggly hesitant fuzzy set (NWHFS), radio frequency stealth, best-worst method (BWM)
