Abstract:

A review is made of the application of sum-difference beam ; techniques to the ATC Radar Beacon System. A detailed error analysis ; is presented for the case of a monopulse azimuth measurement based ; on the existing beacon antenna with a modified feed network. A comparison of the total expected monopulse error with the azimuth error of the existing ATCRBS indicates that there is little to be gained by a monopulse modification. Without beam sharpening, the ; single-reply monopulse accuracy is less than that of the existing ; system. With beam sharpening and/or by using multiple reply information, ; the azimuth error is estimated to be as little as 1 or 2 ; Azimuth Change Pulses (ACP's), compared to 3 ACP's measured error ; for the Common Digitizer. However, the monopulse modification ; implies a considerable increase in system cost and complexity, and ; the estimated accuracy has not so far been demonstrated in the field. ; A monopulse modification for azimuth measurement in ATCRBS therefore ; is not recommended. In terms of fruit reduction, an advantage is ; obtainable by utilizing sum-difference techniques for artificial ; beam sharpening, but other solutions may be preferable.
