A Weak Signal Detection Method Based on Double Time Difference of Arrival Collaborative Mechanism

Abstract

Abstract-Considering the weak signal of partial radiant point, the traditional TDOA(Time Difference of Arrival) detector cannot meet the requirement. A weak signal detection method based on double time difference collaborative mechanism is proposed. In this thesis, the double time difference collaborative detector is designed, and theoretical analysis and mathematical derivation of the performance of the detector is implemented. Then the processing gain is given out. At last, the simulation has confirmed the performance of the detector.
