Given numerous exciting potentials including substantial cost savings, passive multistatic synthetic aperture radar (PMSAR) has been gaining more attention in the radar community. However, PMSAR research efforts such as emitters of opportunity selection thus far have not considered radar position uncertainty. Seeking to fill this knowledge gap, we run Monte Carlo trials to simulate transmitter position uncertainty and examine the effects on the multistatic resolution of radar sets of different geometries, center frequencies and bandwidths. By monitoring the 3dB contour of the multistatic point spread function, we find that the multistatic resolution worsens on average and the data spread grows with increasing levels of radar position uncertainty; the extent of the effects depends on the bistatic pair with predominantly larger position uncertainty. We observe a robust correlation between the effects of position uncertainty and the bistatic angles; and the extent of the effects is determined by the bistatic pair with predominantly larger bistatic angle. Furthermore, we find that the same amount of position uncertainty has less effects on transmitters with high frequencies and large bandwidths; however, including these transmitters does not guarantee better multistatic resolution, especially in the presence of significant levels of position uncertainty. The findings and methods in this work can be immediately applied to enhance the objective functions for the emitters of opportunity selection problem, producing more realistic rankings that account for non-ideal conditions
