针对反辐射无人机采用前沿测向技术无法对抗闪烁诱偏这一难题，通过分析导引头对两点源测向原理入手，提出一种利用长短基线交错提取相位差解算雷达角度实现抗诱偏的方法。该方法提取导引头长基线与短基线接收到合成信号前沿与中部的相位差，通过解算可以确定雷达的方向，通过仿真验证了该方法的有效性。最后描述了导引头区分诱饵干扰与多径干扰的过程，并分不同情况分析了导引头攻击时相位差的选择。

Aiming at solving the difficulty that anti-radiation UAV using technology of front direction finding can’t confront scintillation decoying,the passage comes up with a method that using long-short baseline measure the phase difference to calculate radar angle by analysis theory of direction finding to dual point-source of seeker .The method extracts front and middle phase difference of siginals that seeker’s long and short baseline receive,then radar’s angle is confirmed by calculating in the formula the passage proves it works by simulate.The last part of the passage describes the progress of distinguish between decoy interference and multipath interference,and analyzing phase difference select of seeker in different situation.
