Abstract:

 

Evaluating low probability of intercept  LPI  performance is the first step to design parameters and arrange  radar resources. In the evaluation process it is hard to rely on the intercept receiver?s working scenarios and operating  parameters. On the other hand, indicators that affect the LPI performance of radiating side are difficult to consider  comprehensively. Thus, building an effective evaluation system is crucial. This research considers the natural parameters  of radar extracted from a radiating scenario. Subsequently, a number of criteria are selected, including spatial, time,  frequency domain, polarization status, energy status, and waveform features. A multidomain radar LPI performance  evaluation method is established, which is based on Pythagorean hesitant fuzzy sets  PHFSs . The paper is motivated  by other scholars? research on fuzzy set theories and derives correlation coefficients as well as their properties for PHFSs.  Concretely speaking, this study takes account of membership degree, nonmembership degree, and the hesitation of  decision makers, so it integrates the benefits of correlation coefficients of hesitant fuzzy sets with Pythagorean fuzzy  sets. Meanwhile, weighted correlation coefficients of PHFSs and their properties are proposed in detail. This provides  a feasible approach for evaluation problems. For the sake of application, this article gives the specific LPI performance  evaluation process. Finally, a novel method is presented to evaluate four fire control radars? LPI performances and is  proved to be viable.
