Abstract
A novel approach for broadband microwave frequency
measurement by employing a single-drive dual-parallel Mach-Zehnder
modulator is proposed and experimentally demonstrated. Based on bias
manipulations of the modulator, conventional frequency-to-power mapping
technique is developed by performing a two-stage frequency measurement
cooperating with digital signal processing. In the experiment, 10GHz
measurement range is guaranteed and the average uncertainty of estimated
microwave frequency is 5.4MHz, which verifies the measurement accuracy
is significantly improved by achieving an unprecedented 10−3 relative
error. This high accuracy frequency measurement technique is a promising
candidate for high-speed electronic warfare and defense applications.
