To determine the proper input format to utilize the real-time two-dimensional coherent imaging devices for antenna data processing, the properties of a raster scanned wideband signal are studied. The analysis of the ambiguity function leads to the possibility of two-dimensional processing of raster signals. Holographic filters are designed for multidoppler matched filtering and the array-pattern synthesis of 2-D wideband antenna-arrays, with multiplexing of rastered channels. Complete processing using a single holographic filter is presented experimentally for the case of a Sonar-doppler array antenna, with correlation detection and extraction of the three target parameters range, doppler, direction.
