基于TOEO的频率和真延时可调波形产生方法

针对多种微波光子技术在雷达中的综合运用，提出了一种基于可调谐光电振荡器（TOE0）的频率和真延时独立可调的一体化线性调频波形光产生方法．首先利用可调谐光电振荡器实现频率可调谐，然后通过马赫增一德尔调制器（MzM）对其产生的信号进行脉冲调制，最后经由偏振调制器（PolM）同时实现线性调频与真延时．理论分析和仿真实验证实了所提方法具有频率和真延时独立可调谐的能力．该方法对宽带相控阵雷达波形产生与波束形成具有重要意义．

Generation of waveforms with tunable frequency and true time delay based on TOEO

To improve the operational effectiveness of equipment system, we bring forward the transceiver front-end technique for integration of radar/reconnaissance/jamming based on micro-assembly hybrid integrated design. Through optimization of the frequency conversion scheme and application of the double balanced mixer, the noise coefficient, dynamic range, isolation and other key indices are designed and analyzed, and the transceiver front-end has the characteristics of broadband, high sensitivity, low noise, large dynamic range, compact structure, high degree of integration, light weight and etc., by design and simulation of the amplitude equalizer of the key passive circuit and MEMS filter as well as a reasonable scheme of frequency division. These proposed techniques are already employed in a certain type of radar equipment, which can meet completely the demand of these three operational modes including the radar, reconnaissance and/or jamming, thus having a higher engineering use.
