Conformal phased arrays for Extended Area Tracking System EATS, Target Control System TCS, and Telemetry System TMS are analyzed using computer simulation when they are located on a P-3 aircraft. First, the radiation patterns are obtained by assuming that the array elements are uniformly spaced around the curved surface, and the exact phase is used to scan the beams. To simplify the phase control, a method is discussed by which the phase control is approximated by a planar array, row-column steering. The radiation patterns are obtained using the approximate technique and compared with those obtained by using correct phase control. The results indicate that the approximate phasing can be used witH EATS and TCS arrays with negligible degradation in array performance. For TMS arrays, the simple row-column steering introduces unacceptable phase errors. For such arrays, a modified approximate phasing is recommended.
