摘要
在复杂的战场电磁环境下,毫米波段的雷达信号已投入应用,传统的微波瞬时测频方法难以满足现代电子信息战的需要。采用非相干光纤马-泽微波光子结构,把微波信号调制到光域进行处理,可以实现雷达微波信号0～40GHz的全频段测量,但测频精度有待提高。文中研究了影响瞬时测频精度的因素,对提高测频精度有重要意义。
Due to the complex electromagnetic environment,the traditional methods of the Instantaneous frequency measurement can not meet the need of Modern electronic warfare . It achieves radar signal＇ s full-band measurement of 0 - 40GHz by modulating the microwave signal to the optical domain to process, But the precision of frequency measurement needs to be improved. This paper researchs on the factors influencing the instantaneous frequency measurement precision,and it has important significance to improve the precision of frequency measurement.
