Abstract

A system for making airborne surveys uses first and second surveys made at opposite points on the thermal cycle and collects hyper-spectral image data forming continuous bands in the visible, solar infrared and thermal infrared regions.

Claims

1. An airborne reconnaissance system capable of acquiring contiguous co-registered image data from 0.4 to 2.5 microns in wavelength and from 8-12 microns in wavelength, comprising:

a plurality of electromagnetic energy sensor arrays;

means for receiving and processing data from said sensor arrays;

calibration means for substantially continuously calibrating said system;

platform means adapted to be mounted in an aircraft for carrying said system therein;

means for determining relative flight characteristics of said platform means including the pitch, roll and yaw axes of an aircraft carrying said platform means; and

central processing means for receiving data from said means to receive and process data from said sensor arrays, said means for determining relative flight characteristics and said calibration means to determine electromagnetic spectral image data characteristics for an area being surveyed.

2. The airborne reconnaissance system according to claim 1 further comprising means to view the image data in real-time while airborne.

3. The airborne survey apparatus according to claim 1 and further comprising:

image processing means for further enhancement of the image data.
