    • A system which uses a random noise test target 16 to align sensors 10 and 12 by performing mathematical cross correlations between sensors 10 and 12. The system 48 includes a computer 58 rotating one of the images, computing a correlation between the rotated image and a reference image and determining the peak in the correlation. A global maximum is used to interpolate a true subpixel peak. The interpolated rotational cross correlation peak is used to determine values of two dimensional and rotational movement of one of the sensors 10 and 12 necessary to align the sensors. The values are used to move the sensor 10 or 12 and it is fixed in place. Once the sensors have been aligned and fixed in place, the system 118 computes the cross correlation of segments of the image to determine delay values and an interpolation filter coefficient values which are stored in a permanent storage device 120. The coefficients are used by an correction circuit 122 to correct for regional or spatially varying alignment errors during real time image processing by the imaging system.
