中文摘要:
经分析一类用频装备带内阻塞干扰机理是有用信号湮没于干扰信号,经过接收机由于自适应增益调节,有用信号无法得到相应的放大,因而无法被检出.为预测用频装备在战场的生存能力,由一般接收机的工作原理出发,以有用信号增益为标准,推导出其双频干扰状态下的预测模型.并以某型通信电台为受试对象,以误码率作为电台干扰的评判标准,给出了单频敏感度测试方法以及双频干扰敏感度测试方法,并利用试验数据验证了干扰预测模型的正确性.
English Summary:
The reason of blocking jamming in-band is that the useful signals are buried in interfering signals and can not be detected due to adaptive gain adjustment of some kind receiver. In order to predict the survivability of frequency equipment in battlefield environment, a prediction model was deduced for the dual-frequency interference condition, taking the useful signal gain as standard and adapting the working principle of the general receiver. Taking a certain type of communication station as an example and the bit error rate as the criterion of interference, a single-product sensitivity test method and a dual-frequency interference sensitivity test method were developed for a communication station. The correctness of the interference prediction model was verified with the test data.
