摘要：

In multilateration system, the system's positioning accuracy for a target is directly determined by TOA (Time of Arrival) measurement accuracy of the target signal and the TOA measurement accuracy of target signal is depended on accuracy and stability of the crystal oscillator which provides system clock Aiming at specific problems of TOA measurement accuracy of target signal in multilateration system, the impact of frequency offset of crystal oscillator and GPS pulses per second jitter on TOA measurement accuracy is analyzed, and a correction method for TOA measurement of target signal based on Kalman Filter is derived. Numerical simulation shows that the method can effectively improve the measurement accuracy of target signal TOA, and has relatively strong practical significance and value.
