Abstract

CADDRAD is a radar/radome analysis code meant to aid in the design of modern radar radomes on aircraft. Arbitrary radome shapes may be input in a standard format used by computer-aided-design software. Multi-layered radomes, with thickness tapers in all layers, may be used. The radar may be either electronically or mechanically scanned. The underlying theory implemented in the code is discussed. Comparisons are shown between measurements and predictions of reflection lobes, beam peak loss, and boresight error
