  • In some applications, a target needs to be located by a small-sized mobile platform, such as plane or ship. In this paper, the target is located by a small-sized mobile platform assisted by an array in the base station, which could work together under two modes: Multiple-Input Multiple-Output (MIMO) mode and Multiple-Input Single-Output (MISO) mode. The geometric model is established. Also, the Geometrical Dilution Of Precision (GDOP) of the relative coordinating errors of the target are formulated and factors affecting GDOP are analyzed under the two modes respectively. Simulation results show that: under MIMO mode, the GDOP is irrelevant neither to the azimuth of the target nor to the location of the small mobile platform; the location precision under MIMO mode is higher than that under MISO mode when the small mobile platform is far from the target or the number of array elements is large; however, lower when the small mobile platform is close to the target and the number of array elements is small.
