基于熵损失度的测速测距抗干扰性能评估方法

在跳扩频测控系统的测速、测距抗干扰性能评估中引入熵的概念。在信息准则下,以熵损失度作为评价指标,建立抗干扰性能评估模型,推导出熵的变化与干扰功率、干扰因子等参数的数学关系。仿真结果表明了熵损失度随着干噪比和干扰因子的正比例变化趋势,并且得到了不同干扰参数在一定熵损失门限下的制约关系。

Evaluation Method for Velocity and Distance Measurement Anti-jamming Performance Based on Entropy Loss

The concept of entropy is introduced into evaluation for the performance of velocity and distance measurement anti-jamming in DSSS/FHSS Hybrid Spread Spectrum TT C System, establishing an evaluation model in which the degree of entropy loss is used as an index under the rule of information, and analyzing the impact on the index from the changing ofS jamming parameters. The feasibility of using entropy loss degree as an evaluation index isSverified by simulation.
