Abstract:

The studies leading to the development of an electro-optical signal processor for the Synthetic Spectrum Radar are continued. During this period the single channel experiments have been extended to the production and evaluation of photographically recorded signals. An electro-optical system to precisely expose and evaluate photographic film is described. Amplitude transmittance versus exposure energy curves for Kodak type 2479 film are shown for parametric values of development time. These curves are used to establish the bias point exposure for the single channel recorder system. Film recordings of a 20-MHz CW signal as a function of transducer input voltage were then made. A second coherent optical system which reads out the recorded signal is then described. The film reader output shows that a 30-dB dynamic range was obtained.
