英文摘要：

Precise time difference measurement is widely used in the fields of laser rangefinder, passive TDOA location, aviation remote telemetry,the time difference measurement method based on TDC is proposed and the precise time difference measurement system based on TDC- GP1 is designed. Besides,the method of system design, the software and hardware circuit principles are given. The system has some advantages, such as flexible configuration, high reliability and low power consumption. The analysis shows that the system can achieve ns-level time interval measurement.
