INSTANTANEOUS FREQUENCY MEASUREMENT (IFM) CORRELATOR USING OPTICAL APPROACH

THE IFM IS ALMOST AN IDEAL RECEIVER FOR THE INTERCEPTION OF RADAR THREATS EXCEPT THAT IT CANNOT PROCESS MULTIPLE SIMULTANEOUS SIGNALS. A RECENTLY PROPOSED APPROACH USING CORRELATOR ARRAY SHOWS GOOD POTENTIAL OF RESOLVING THIS MAJOR DEFICIENCY. THIS PROPOSED EFFORT IS TO INVESTIGATE, ACCESS AND COMPARE DIFFERENT OPTICAL SIGNAL PROCESSING TECHNIQUES FOR THE IMPLEMENTATION OF IFM CORRELATORS. SEVERAL INCOHERENT AND COHERENT CONFIGURATIONS USING FIBER-OPTIC, ELECTRO-OPTIC AND ACOUSTO-OPTIC TECHNOLOGIES ARE PROPOSED. SYSTEM ANALYSIS AND EVALUATION WILL BE PERFORMED ON THE FEASIBILITY OF THE PROPOSED CORRELATORS. AN OPTIMUM DESIGN FEASIBILITY DEMONSTRATION MODEL WILL BE PURSUED IN THE SECOND PHASE EFFORT.
