<p>A method of and a means for acousto-optic signal processing for electronic support measures in which a signal is received on a two element spaced array (E1-E2) antenna and applied to Bragg cells (BC1-BC2) in a Mach-Zehnder interferometer to produce a first optical beam (P1) from one element of the array (E1), and a second beam (P2) which is a combination of the signal from the first element (E1) and the second element (E2) of the array, and passing the beams through opto-electrical transducers (L1-L2) and linear photo detector (D1-D2) to a computer.</p> |
