Research on target location technology based on long baseline (TDOA)

In the sea test range, the accurate measurement of the landing point of weapons and equipment is the key issue to assess the strike accuracy. In order to improve the accuracy measurement of the landing point of weapons, this paper studies the long baseline (TDOA) landing point target positioning technology, and analyzes the positioning accuracy and simulates the location of the landing point target based on the landing point measurement scenario. The design index of the actual test verification system in the deep sea area of the South China Sea is analyzed, and the test results prove that the system can display the position of the falling target in real time and has relatively high precision positioning results, which provides technical support for the accuracy measurement of the falling point of weapons and equipment.
