Investigation of Complex Angle Processing to Reduce Radome Induced Angle Pointing Errors

摘要

This work is an analysis of the effect of a tangent ogive radome on the pointing accuracy of a monopulse radar that employs an aperture antenna. The incident fields at the antenna are found by a ray-tracing procedure. the theory of monopulse radar and the transmission and reflection properties of planar dielectric slabs are presented. Two orthogonal polarization states which can be combined to produce an arbitrarily polarized incident field are considered. The antenna can be scanned in two angular directions and radar pointing error is presented for both these angles as a function of antenna scan angle and polarization of the incident field. A method that can be used to compensate for radome-induced error is presented. Complex angle processing for the purpose of pointing angle reduction was investigated. (Author)
