The invention provides a terahertz broadband radar micro-Doppler ambiguity resolving method based on intrapulse interference. The method is used to realize micro-Doppler ambiguity resolving based on intrapulse interference through utilizing the characteristic of receiving a signal through a broadband radar dechirping manner (Dechirp), and has the characteristics of high efficiency, safety and the like; meanwhile, systematic complexity is not increased. 本发明提供种基于脉内干涉的太赫兹宽带雷达微多普勒解模糊方法，通过利用宽带雷达解线频调方式(Dechirp)接收信号的特征，基于脉内干涉实现了微多普勒解模糊，具有高效稳健等特点，且同时不增加系统复杂度。
