Abstract
A system and method for using orthogonally-coded active source signals for reflected signal analysis, such as in seismic exploration, sonar, and/or ultrasound applications. One method comprises inputting an orthogonally-coded active source signal to a target site, where the orthogonally-coded active source signal is sufficiently random to not interfere with a delayed version of itself. A reflected signal is received from the target site, and based at least in part on the sufficiently random orthogonal coding of the active source signal, a determination is made whether the received signal is a reflection of the input active source signal.
Claims20
A method comprising:
- inputting, by a source device, a sufficiently random, orthogonally-coded active source signal to a target site;
- receiving, by a receiver device, a received signal reflected from said target site;
- and
- determining, based at least in part on sufficiently random orthogonal coding of said orthogonally-coded active source signal, whether said received signal is a reflection of said input orthogonally-coded active source signal.
A method comprising:
- inputting, by a plurality of source devices, a plurality of orthogonally-coded active source signals to a target site, wherein said orthogonally-coded active source signals are sufficiently random so as not to interfere with delayed versions of themselves occurring within an operational time window;
- receiving, by at least one receiver device, a plurality of received signals reflected from said target site;
- and
- correlating, based at least in part on sufficiently random orthogonal coding of said plurality of orthogonally-coded active source signals, said plurality of received signals with said plurality of input orthogonally-coded active source signals.
