中文摘要	被动遥感技术的发展对复相关器提出了新的要求,而模拟复相关器具有灵敏度高,体积小,功耗低等优点.在此重点介绍了复相关器的核心部件:乘法器单元和宽带移相器;模拟了点频上的相位反演并分析其反演能力;测试了模拟复相关器的宽带相位特性,模拟了宽带相位反演过程并测得其相位反演精度
英文摘要	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 of the correlator and simulated broadband phase-inversion process. The result of phase inversion accuracy has been given
