Three-dimension imaging is a hot topic. And the near-field imaging is a new kind of measurement technique, which has been widely used in radar measurement. Based on Nyquist criterion, the spatial and frequency sampling criterion is established in near-field microwave imaging. First, the principle of the experiment was introduced, particular analyses on simple point-target were given, and the method to improve working frequency had been received, through changing the geometry relation of the sampling spatial. A statistics on one typical experiment condition was presented, and an analysis of multi-target and three-dimension target was implemented, compared with point-target, and get the method to predigest the complex target to the point-target by changing the geometry. This will make the experiment easier and more efficient.
