Appendix 5: Glossary

This glossary provides assistance in understanding terms used in this book. There may be more general, more specific, or entirely different meanings for these terms when they are used elsewhere.

Adaptive array:: an electronically steerable antenna designed to respond automatically and optimally to a variety of situations
Adaptive receiver:: a receiver with circuitry or perhaps programming that enables it to adjust to the characteristics of the incoming signal
AGC:: automatic gain control, keeping the excursions of the received signal within bounds with an automatic negative feedback loop
Ambiguous angle:: an angle where the characteristics of an antenna pattern are such that there is uncertainty about the angular location of a target (as with an interferometer)
Ambiguous range:: the condition that the round-trip time between pulses is insufficient to accommodate all the targets that the radar will see, resulting in uncertainty about target range
Ambiguous range rate:: the situation that occurs when the Doppler processing scheme of the radar is such that target range rates fold over, making those range rates uncertain
Ampere s law:: current passing through a conductor creates a magnetic field around the conductor; named after the man who discovered the phenomenon
Amplitude:: the height of a trace on a display or record, usually referring to a measurement of voltage or power
Analog error signals:: indicators derived from a continuous process that permits correction while the process is going on, as with a radar beam tracking a target
