Abstract
An electromagnetic (EM) receiver system for measuring EM signals. The EM receiver system includes a platform; a coil for measuring EM signals; and first to third suspension mechanisms located between the platform and the coil so that the coil oscillates relative to the platform, and the first to third suspension mechanisms attenuate motion induced noise introduced by towing the receiver system above ground.
Claims15
An electromagnetic (EM) receiver system for measuring EM signals, the EM receiver system comprising:
- a platform;
- at least one coil for measuring EM signals;
- a coil support to which the at least one coil is fixedly attached;
- and
- first to third suspension mechanisms located between the platform and the coil support so that the coil support oscillates relative to the platform, and the first to third suspension mechanisms attenuate a motion induced noise introduced by towing the receiver system above ground,
- wherein the first suspension mechanism is located within the coil support and the second and third mechanisms are located outside the coil support.
A method for attenuating motion induced noise in an electromagnetic (EM) receiver system for measuring EM signals, the method comprising:
- providing a platform;
- and
- fixedly attaching at least one coil for measuring EM signals to a coil support and attaching the coil support to the platform with first to third suspension mechanisms,
- wherein the coil support oscillates relative to the platform, and the first to third suspension mechanisms attenuate the motion induced noise introduced by towing the receiver system above ground, and
- wherein the first suspension mechanism is located within the coil support and the second and third mechanisms are located outside the coil support.
