Interferometric measurements are carried out in conventional manner to produce a correlogram corresponding to successive scanner steps. In conjunction with a vertically polarized array, a particular high-gain wireless environment may be created such that one environment does not interfere with other nearby wireless environments and avoids interference created by those other environments. A recording apparatus is configured to take a detectable state and an undetectable state. When the initiator module meets conditions for standby mode, the initiator module sends a standby signal to the PCCM and does not interact with other initiator, target, or interconnect modules. The invention also relates to a projection radiography or x-ray computer tomography system which features programs in a processing system which executes the method described above when the system is operating.
