Development of Analog Complex Correlator and Its Performance Test
模拟复相关器研制及其性能测试

Passive remote-sensing technology requests high performance of complex correlator.An analog complex correlator has been introduced in this paper,The advantages of this correlator are low power consumption(compared to a digital correlator),small chip area and high sensitivity.Core components of the analog complex correlator are multiplier unit and wideband phase shifter,their manufacture and performance have been discussed and the results have been presented.We have tested the broadband phase characteristic ...
