%X The AeroTEM system?s rigid structure and bucking coil makes the recording of interpretable on-time data possible. When processed using standard methods the on-time dB/dt response is comparable in conductivity aperture to the off-time calculated B-field response. However, standard primary field removal methods distort both on-time dB/dt and calculated B-field responses. By modifying primary field removal routines to incorporate the rigidity of the system it is possible to minimize these distortions. While this directly improves dB/dt and calculated B-field responses, it opens the door to other advanced processing techniques that require the accurate removal of the primary field such as the detection of perfect conductors. Initial results from synthetic and field data are used to illustrate the potential of these routines.
