摘　　要：相位差变化率定位是利用载机与辐射源的相对运动信息实现无源定位的一种方法。首先介绍利用相位差变化率对固定辐射源定位的原理,然后重点讨论航向角及其变化率对相位差变化率、定位精度的影响,并利用实测数据进行定位计算,验证了相关结论及该定位方法的有效性。A stationary emitter can be located using phase difference rate of change, which is caused by relative motion between receivers and emitter. The localization principle is introduced firstly,the effects of heading and its rate on phase difference rate of change and location accuracy is analyzed in detail. The experimental results based on measured data demonstrate that the method is effective.

关 键 词：无源定位 相位差变化率 定位误差 航向角
