#Abstract:

Observation of the two source models: M51 with spiral expanded structure and 
methanol masers with cluster of compact sources, has been simulated, observed 
by the two arrays of 64 antennas (12 meter diameter each) at snapshot mode with 
random pointing error of the antennas. The two configurations: the doughnut and 
the ring have been considered.
The size of the source is equal to a half of the antenna primary beam.
The rms of the  pointing error was in the range (0-20)\% of the primary beam 
width. The quality of the restored image is aggravated with increasing the 
pointing error. The better of the two configuration stays to be better for 
any pointing error although the difference is becoming small for the large 
pointing error.
