Overview

The models in this book use the metric system [International System of Units (SI)], also known as the mks system (for meter-kilogram-second). This allows for standardization and simplification of the equations. However, many of the examples, problems, and custom radar functions use units that are common to radar usage. For example, power may be specified in kilowatts instead of watts, and radar cross section may be specified in decibels relative to a square meter, rather than square meters. This appendix provides factors that can be used to convert other units to the metric system. It also provides other useful conversion methods and values for constants used in the book.

Factors for converting measurements into the metric system are given in Table D.1. Conversion in the opposite direction can be done by dividing by the factor given.

Unit prefixes, their abbreviations, and their meanings are given in Table D.2.
