ABSTRACT:
Samples of signals received by elements responsive to incident radiation, such as an array of sonar transducers, are obtained as exponents of the base two by a successive approximation register and decoder coupled together in a feedback loop by a comparator and a digital-to-analog converter. Weighting of samples from the individual transducers is obtained by adding scaling exponents to the sample exponents. Combining of samples to form a beam of received radiation is accomplished by summing together the antilogarithms of selected weighted samples.
