Analysis of Noise Jamming Effect on Tri-Station Passive TDOA Location System

Based on the principle of noise jamming,the situations of the same reconnaissance station interfered by the different intensity noise and different reconnaissance stations interfered by the same intensity noise are analysed,and the jamming effect is simulated sequencely.The simulation results show that the noise jamming effect on tri-station passive TDOA(Time Difference of Arrival) location system becomes better as the interference power and information power ratio received by reconnaissance station becomes bigger,and that the noise jamming effect on primary station is better than on assistant station.This provides a new way to protect the location of radiation source actively.
