Abstract : The report introduces a signal processor structure for synthetic array processing in conjunction with a random signal radar. Displayed in its elemental form, the processor configuration consists of a bank of cross-correlators followed by a tapped delay line. Each correlator reference input is delayed an amount appropriate to focus the synthetic array, and the delay line taps are spaced in accordance with synthetic array element positions. The system is particularly characterized by a complete absence of range and azimuth ambiguities and its capability of operating in real time. It is shown that this system exhibits azimuth resolution properties similar to those of conventional synthetic aperture radar systems. (Author)
