| 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. |
