Method of eliminating spurious signals and a relative navigation system

摘要

A relative navigation system and a method of eliminating spurious signals that may be received by a relative navigation system having a first object and a second object including projecting polarized light having a first orientation to form at least one grid line projecting into space from the first object.

1. A method of eliminating spurious optical signals received by a relative navigation system, the method comprising:
projecting into space from a grid generator, on a first object, a polarized light having a first orientation to form at least one optical grid line for an optical grid defining a first relative reference frame; detecting, by a detector module at a second object having a second relative reference frame, the polarized light having the first orientation; and filtering, at the second object, polarized light having a second orientation, which is different from the first orientation to eliminate spurious optical signals having the second orientation, which would otherwise appear as directly propagated light signals to the detector module; and wherein the detector module determines its position within the first relative reference frame based on the detected light having the first orientation.
