Evaluation Method for Anti-Interference Performance of Measuring Based on Entropy Loss

Article Preview

Abstract:

The concept of information entropy is applied to evaluation for anti-interference performance of velocity and distance measurement in DS/FH hybrid spread spectrum TT&C (Tracking, Telemetry & Command) system, establishing an evaluation model where the entropy loss degree is used as an index under the rule of information, and analyzing the impact on the index from the changing of interference parameters. The feasibility of using entropy loss degree as an evaluation index was verified by simulation.
