Abstract
OFFERED HERE IS A PARAMETRIC STUDY OF AN ALGORITHM FOR DETERMINING TARGET RANGE FROM A SEQUENCE OF TARGET DIRECTION ANGLES AND TARGET EMISSION FREQUENCIES AS ACQUIRED AT A SINGLE-SITE, PASSIVE ESM RECEIVER FACILITY. THE ALGORITHM, WHICH FORMALLY ADJOINS THE LATERAL INFORMATION CONTENT OF THE ANGULAR DATA TO THE RADIAL INFORMATION CONTENT OF THE FREQUENCY DATA, WAS SUCCESSFULLY DEVELOPED TO ENABLE THE PASSIVE SONAR TARGETING OF HOSTILE SUBMARINES BY OUR OWN. IT CAN BE EASILY ADAPTED TO THE PASSIVE, SINGLE-SITE ESM CASE. ITS PRACTICAL UTILITY IS TO BE ASSESSED BY THE GRAPHICAL PLOTTING OF SUCH PERFORMANCE ATTRIBUTES AS ONE-SIGMA RANGE ERROR VERSUS SUCH ESM TRACKING ATTRIBUTES AS (A) ANGULAR SPAN, (B) TIME SPAN, (C) FREQUENCY SPAN, (D) ANGULAR AND FREQUENCY ERROR VARIANCES, (E) SPAN GEOMETRY, (F) DATA RATE, AND (G) OMISSION OF EVALUATION DATA, TROPOSPHERIC REFRACTION. TIME AND ACCURACY WISE, IT IS KNOWN THAT THIS TECHNIQUE CANNOT COMPETE WITH AN ACTIVE RADAR. HOWEVER, IT IS PASSIVE AND, IN ADDITION TO RANGE, ESTIMATES THE COMPLETE TARGET STATE VECTOR. RELATIVE TO TRIANGULATION METHODS, IT OFFERS THE CONSIDERABLE ADVANTAGE OF SINGLE-SITE AUTONOMY.
