Abstract:

The far field pattern degradation of space fed phased arrays suitable for a space based radar is examined. The effects considered are Structural 1 Axial lens surface distortions, 2 Uniform radial thermal expansion, and 3 Axial and lateral feed displacements Electrical 1 Element phase and amplitude excitation errors, and 2 Failed elements. An introductory section discusses the size, cost, and weight penalties of low sidelobe designs. The final section presents a method of phase compensation or coherence of large axial lens distortions.
