In view of the problem that multi-base station radar system can not be regularly deployed due to the influence of topographic factors or mission conditions in practical engineering, the system positioning accuracy under various irregular station distribution conditions is analyzed by theoretical simulation in the current study. The influence of irregular station distribution on the system positioning accuracy is investigated from three aspects including the baseline length, the angle between baselines and the height difference between base stations. The location accuracy distribution law of the system in different locating areas under various conditions of irregular station distribution is obtained, which provides a theoretical basis for site selection of multi-base station radar in practical engineering.

Key words: passive location, time difference system, irregular station layout, location accuracy, accuracy analysis, GDOP
