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.

Abstract: An apparatus for generating an intermediate voltage having a value between a positive voltage supply value and a negative supply value. The apparatus has low power dissipation and is dynamically stable over a range of external supply voltages. The apparatus comprises a voltage comparator having first and second input terminals and a control signal output terminal. A reference voltage generator is coupled to the positive voltage supply and generates a reference voltage which is coupled to the first input terminal of the comparator. A device having a zener characteristic is coupled to the positive voltage supply and generates a voltage which is coupled to the second input terminal of the comparator. A current source is coupled to the negative voltage supply and generates a current which is coupled to a terminal, to form the intermediate voltage, and is also coupled to the device to determine the voltage generated thereby.
