This paper presents a FORTRAN language radar detection model that determines the signal-to-noise (S/N) ratio as a function of target range. The model determines S/N ratios in a clear or noise jamming environment. The jamming may be created by a self-screening or standoff jammer operating against the radar in the main-lobe and/or side-lobe. The threats may have an ascending, level, or descending flight profile. The effects of atmospheric attenuation, weather clutter, sea state, surface clutter, and multipath may also be considered.

Estimating character error rate by comparing send and receive character streams is described and evaluated.

The Navy Resource Model (NARM) is a system of computer programs which provides the capability to cost a total Department of the Navy program. Attached to the basic cost model are many peripheral programs that serve important functions. This paper focuses on the use of one such program, UPDATE. UPDATE's function is to provide the NARM user with a flexible method of changing the data base. It is intended to be a guide for the new or casual user as well as a reference for the experienced user.

The Aircraft Force Projection Model (AFPM) is designed to project the Navy's aircraft inventory over a ten-year period and attempts to satisfy the operating requirements of a given set of forces with the projected operating inventory. In addition the AFPM generates useful characteristics of the aircraft inventory such as projections of the age distributions, attrition quantities, pipeline requirements, and rework requirements. This volume describes the input data file, file maintenance procedures, and how to run the model. The Aircraft Force Projection Model (AFPM) is documented in two volumes. Volume I, The Users Guide, describes the input data file, file maintenance procedures, and how to run the model. Volume II, The Programmers Guide, contains a detailed explanation of the AFPM computer programs and program listings.
