1. A method of calibrating a remote sensor system comprising the steps of:

  • (a) mounting at least one remote sensor on a vehicle;

    (b) moving the vehicle in a self-locking pattern over a target area to calibrate the remote sensor, the movement comprising any pattern that produces at least three substantially parallel travel lines out of a group of three or more lines, at least one of which travel lines is in an opposing direction to the other substantially parallel travel lines;

    (c) generating swath widths for each substantially parallel travel line with the remote sensor device;

    (d) collecting remote sensing data of the target area during vehicle movement;

    (e) inputting the remote sensing data into a computer to calculate calibration data; and

    (f) applying the calibration data to the remote sensing data to remove bias in a displayable image output or in an electrical strength signal.
