To accurately detect slow‐moving vehicles, we have developed a new correlation technique which employs multiple sensors (two sensors with an along‐track orientation and two sensors with an across‐track orientation). Unlike conventional MTI (moving target indicator) radar, our technique makes use of the Doppler‐shifted phase of the correlation of the scattered waves. ©1999 John Wiley & Sons, Inc.
