Abstract:

This report summarizes the initial theoretical and experimental studies of the electro-optical signal processor for the synthetic spectrum radar. The present digital radar processing is briefly reviewed. The proposed electro-optical processor technique is presented. This processor operating in real-time is capable of coherently phase-referencing and continuously recording the multi-channel radar output on photographic film. An experimental, single- channel, CW-signal recorder system is described. Preliminary experimental results are included which verify the electro-optical recorder theory and show that the recorder output light intensity distribution corresponds to the input signal. The investigation of wide band solid light modulators for optical signal processors is continued. The theory of optimal transducer depth to minimize internal refractive effects is verified experimentally for the compression mode. Additional experimental data on the cross coupling between 0.5 mm spaced transducers shows no evidence of cross coupling to within 20 db for compression mode transducers. Wider separations may be necessary if shear mode transducers are employed.
