20160041256 | SYSTEMS AND METHODS FOR USING COHERENT NOISE FILTERING - Systems and methods are provided for the filtering of coherent noise signals. In an illustrative embodiment, a pulsed electronic signal receives varying phase shifts for each of its pulses prior to transmission. When coherent noise interferes with the transmitted signal, received signal receives a phase shift opposite of that applied prior to transmission such that the electronic signal is restored and the coherent noise becomes non-coherent. In another embodiment, width of each transmitted pulses can be varied prior to transmission, but a constant midpoint-to-midpoint time is maintained. After receiving a signal with coherent noise interference, the midpoints of the pulses are aligned causing the coherent noise to become non-coherent. | 02-11-2016 |
