摘要
针对时分多目标干扰效果的影响因素,从功率角度对其进行了公式推导,以干扰机发射功率、干扰占空比为变化参数,以话音可懂度、频谱失真测度为干扰效果评判指标,建立了调幅话信号时分法干扰仿真模型,通过仿真计算,得出了干扰机发射功率、干扰占空比与干扰效果的关系。
The influencing factors of time-sharing multi-target jamming were analyzed by means of formula derivation of jamming power.The time-sharing jamming model of AM speech signal was established,with the emission power and the duty ratio of jamming as the variable parameters.The speech intelligibility and spectrum distortion were used to evaluate the model.The relationship between the emission power,the duty ratio of jamming and the jamming performance was found by studying the model.
