PROCESSING TECHNIQUES

DIRECTION FINDING OF SIGNALS OF INTEREST IN THE PRESENCE OF CO-CHANNELINTERFERING SIGNALS, WHICH MAY VARY IN PULSE WIDTH, MODULATION TECHNIQUE OR BE CONTINUOUS WAVE (CW), REQUIRES AN OPTIMIZED RECEIVER AND SIGNAL PROCESSING SYSTEM. THE INCREASING DENSITY OF THREAT EMITTERS COUPLED WITH THE EMPLOYMENT OF MORE COMPLEX WAVE FORMS (PULSE COMPREHENSION, AND PULSE CODING, ETC.) MADE POSSIBLE BY ADVANCING TECHNOLOGY, MAKES DETECTION, PROCESSING AND ACCURATE DIRECTION FINDING EXTREMELY DIFFICULT. SPARTA, PROPOSED TO ANALYZE THE SUBJECT PROBLEM APPLYING THE LATEST IN TECHNOLOGY EVALUATING, CHANNELIZED AND COMPRESSIVE TECHNIQUES AS WELL AS DIGITAL FILTERING AND TIME DIFFERENCE OF ARRIVAL TECHNIQUES. THESE TECHNIQUES MUST IN THE AGGREGATE EFFECTIVELY DETECT, PRESERVE PHASE, ASSIGN TIME OF ARRIVAL TO REJECT INTERFERENCE AND ASSIGN DIRECTION TO PULSES OR SIGNALS OF INTEREST. SPARTA INTENDS TO CARRY THESE ALTERNATE SOLUTIONS EITHER PART WAY OR THROUGHOUT PHASE ONE (DEPENDING ON THE CUSTOMER'S DIRECTION) IN ORDER TO ENSURE ADEQUATE EVALUATION OF THE PROBLEM AND PROVIDE COMPARATIVE AND PARAMETRIC ANALYSIS.
