ABSTRACT:
A dual integration circuit is disclosed for extending the dynamic range of on focal plane signal processor used in a space based infrared detection system. The circuit comprises an input port in connection with a dedicated detector element and first and second integration circuits operative to generate an output signal responsive to a detected infrared image. The first and second integration circuits are provided with associated switching circuitry for generating output signals at different times to facilitate detection of objects having bright and dim infrared images.
