Abstract
The invention relates to a target-detection and target-alignment device for a missile system whose field of view is expanded by a wide-angle lens system, which does not contain any optical components which must be additionally moved, and which is equipped with an integrated system for correction of homogeneity of the ambient conditions. Two radiometers or photometers are connected to two emission surfaces positioned on opposite sides of the image of the field of view to adjust the angle of the target detector to compensate for mismatch of the output signals of the emission surfaces.
Claims5
A target detection device for a missile system comprising:
- an adjustable target seeker head mounted on a missile, said target seeker head including an imaging sensor producing an image of a target along an axis disposed obliquely with respect to an axis of the missile,
- a wide angle lens system including an afocal lens system positioned to receive the image from the target seeker head to produce a wide angle image thereof, said afocal lens system having an optical axis substantially parallel to the axis of the missile,
- an external monitor for target marking and tracking,
- a signal transmission system connected to the target seeker head to transmit to the monitor said wide angle image,
- radiation sensor means for sensing ambient radiation, and
- two auxiliary surfaces adjacent to and on opposite sides of said a focal lens system, said auxiliary emission surfaces receiving radiation signals from said radiation sensor means to correct non-uniformity of ambient radiation.
