英文摘要：

Aiming at 3-aircraft 3-dimensional sensor placement optimization, the accuracy factor was taken as objective function and sensor placement was studied from the pointview of the placement plane rotation. And then, based on the modeling and simulation strategy, the placement plane rotation effect was analyzed on the location precision of time difference of arrival （TDOA） localization, frequency difference of arrival （FDOA） localization and hybrid TDOA/FDOA localization, which revealed the rules of sensor placement optimization under different types of localization systems. These rules could be very useful to three-dimensional sensor placement optimization when these were associated with particle swarm algorithm, simulated annealing, genetic algorithm and so on.
