摘要：

In order to describe the simulation error in more detail, the two-dimensional joint probability density function (PDF) of simulation angle error of hardware in the loop radio frequency simulation based on triples is studied in detail, and the directional distribution of simulation error is given. Based on the center of gravity formula, the joint PDF of simulation angle error in two angular directions is given on the basis that the relative error of feed amplitude satisfies Gaussian distribution. The results show that the two-dimensional joint PDF has different simulation errors for point targets in different directions. The simulation angle errors in the two angular directions will have correlation, and the correlation will vary with the position of the point target. Because the angle errors parallel to and perpendicular to the track have different effects on the system, this work is conducive to a more detailed evaluation of the equivalence of hardware in the radio frequency simulation. © 2022, Editorial Office of Systems Engineering and Electronics.
