测相位差变化，卒无源定位技术具有定位精度较高，定位速度较快等优势，在军事上具有较高的应用前景，可以应用于射频告警，获取目标位置情报，或引导武器攻击等。国内外对此技术都很重视，目前正在开展广泛研究和工程实现。文中对这一技术进行综合评述，介绍了测相位差变化率无源定位技术在国外的发展情况，重点介绍了该无源定位技术在国内的发展，包括这位模犁建证、定位性能分析、定位算法改进、相位差变化率测量、载机姿态变化的影响等。指出目前对该项技术研究存在的主要问题及进一步研究方向，这对后续的研究者将有参考作用。

Passive location usign phase rate of change has many advantages, such as high precision, quick location and so on. There fore it has good prospect in military application, for example, RF warning, getting target location, or directing weapon attack etc. This technology is hot in the world. Extensive research and engineering is developed. This technology is introduced in many aspects in the paper. Development of this passive location technoogy in the world is introduced, also as a key introduction in China, including location modeling, performance analyzing, algorithm modifying, measurement of phase rate of change, and influence of attitude angle of the carrier. Some main problems of this field is proposed, which possibly are research focuses in the future, and the author hopes it will be hepful to latter researchers.
