摘要： An array antenna is provided that operates at high-band and low-band, comprising a first array of high-band radiators and a second array of low-band radiators, each respective low-band radiator disposed so as to be interleaved between the high-band radiators so as to share an aperture with the high-band radiators. Each low-band radiator comprises a coaxial section, a dielectric section, a waveguide, and a planar section. The dielectric section is formed of a continuous piece of dielectric material and includes a hollow opening formed perpendicular to the coaxial section, and a plurality of step transitions, wherein at least one of the step transitions is disposed within and partially fills the waveguide operably coupled to the planar section. The planar section is oriented to the portion of high-band radiators such that the output of the respective low-band radiator is disposed between and within the spacing between adjacent high-band-radiators.

摘要： A multi-mode seeker which comprises a stationary antenna and electronic circuitry responsive to signals received by the antenna to cause the antenna to scan a field of view determined by the signals received by the antenna. The seeker has a nose region positioned at the forward portion thereof and an adjunct sensor disposed in the nose region ahead of the antenna. The electronic circuitry includes circuitry for performing a Sum/Delta monopulse processing technique on the signals received by the antenna the Sum/Delta monopulse processing including calculating each of a standard Sum signal, Delta-Azimuth signal and Delta-Elevation signal. The seeker has a boresight axis, the center of the field of view being off boresight, in general. The seeker has a field of regard, the field of regard having plural sectors, each of the sectors having separate predefined compensation.
