M-layer: NPS version
Abstract
The M-Layer program developed by NOSC has
been substantially revised into a Naval Postgraduate School (NPS) version. The mode locating algorithm was re-written to
take advantage of I d an alyticity of the mode function. The
exponential complex number representation was adopted to
simplify multiplication and to improve accuracy when adding
two complex numbers which nearly cancel each other. A
consistency condition was formulated to assure accurate and
efficient evaluation of the height-gain function. As a result, this
NPS version executes faster with greater stability.
