摘要
通过对基于相位调制的瞬时微波频率测量系统结构的分析,在Optisystem仿真软件平台上进行了详细的结构仿真和器件参数设定值分析。通过根据输入的不同载波波长得到的分段测量结果值,在总测量频程6~18GHz范围内,最低精度可达到0.1GHz,使得到的测量频率值相对于特定频段更具有代表性。通过检测输出端功率比,求得待测频率,实现了测量频程在6~11GHz时,测量精度总体约为0.5GHz;测量频程在11~15GHz时,测量精度总体约为0.2GHz;测量频程在15~18GHz时,测量精度总体约为0.1GHz。
According to the analysis on the system structure of the microwave instantaneous frequency measurement based on phase modulation, detailed structure simulation and analysis of device parameters are performed on Optisystem software. With different input carrier wavelengths, section measurement results are obtained. Within the measurement range of 6-18 GHz, the lowest error is 0.1 GHz. The unknown frequency is got from detecting the ratio of output power, and measurement errors of about 0. 5 GHz, 0.2 GHz and 0. 1 GHz are realized for the measurement ranges of 6-11 GHz, 11-15 GHz and 15-18 GHz, respectively.
