摘　　要：在被动导引头中,角度信息是由微波接收机接收并由后续信号处理机处理后得到的,方法多采用单脉冲体制的相位测向法,相位测向的关键是相位的准确性,由于被动体制工作带宽较宽,增加了系统相位指标的设计难度,需要通过相位补偿的方法提高测角精度。文章介绍了一种用于被动导引头宽频带测向系统的相位补偿方法,分析了方法的可行性,并给出了试验结果。In passive seeker,the message of direction angle can be received by microwave receiver and then be processed by signal processor which usually used single pulse direction finding method by phase.The precision of phase is the key aspect in this method.Because of the broadband speciality of passive seeker,phase design of the system is very difficult.The method of phase compensation can be used to enhance the precision of the phase angle measurement.This paper introduces a novel method of precision phase compensation which used in broadband direction finding system of the passive seeker.The feasibility of this method is analyzed,and the result of experimentation is given in this paper.
