Abstract:

The research program for an electro-optical signal processor for phased array antennas is continued. In this phase of the program, particular emphasis is placed on the spatial multiplexing technique and the resulting sidelobe response of the system. The theoretical envelope response for a cosine amplitude weighted aperture utilizing a channel separator mask is presented. New techniques and equipment developed to facilitate the measurements of the resolution and sidelobe response of the system are discussed. This includes the 24-channel input signal simulator, the mechanical scan mechanism, x-y recorder and a 40-db dynamic range photomultiplier circuit. Author
