Abstract:
The qualitative relation between boresight-error characteristics of a streamlined radome and the planewave transmission properties of plane dielectric sheets and sandwiches is discussed. To minimize the boresight errors, a radome wall structure should be selected which has small values of dd theta absolute value of T and d d thetaIPD, where , absolute value of T is the magnitude of the transmission coefficient, IPD is the insertion phase delay, and 0 is the angle of incidence. To facilitate the preliminary design of the radome wall structure, data on absolute value of T squared, dd theta absolute value of T and dd thesa IPD are presented in graphical form for thin walls, half-wave walls, and sandwiches. The data cover a range of requencies and angles of incidence. It is noted that the properties of the radome wall structures considered here are significantly better for parallel polarization than for perpendicular polarization. This suggests that a useful reduction in boresight error could be obtained by automatically controlling the polarization of the radar antenna as it scans in various directions. Author
