// UNMANNED SYSTEMS AND NEXT-GEN WARFARE TERM
LPI
LPI refers to electronic signals, like those from radar or radio communications, that are designed to be very difficult for enemy forces to detect or intercept. This helps maintain secrecy and operational stealth.
TECHNICAL DEFINITION
Low Probability of Intercept (LPI) is a characteristic of radar or communication signals engineered to minimize their detectability by adversary electronic support measures (ESM) or electronic intelligence (ELINT) systems. LPI techniques, such as spread spectrum, frequency hopping, low power, short pulse durations, and directional transmissions, enhance stealth and survivability for platforms engaged in electronic warfare (EW) and signals intelligence (SIGINT) environments.
BACKGROUND
This subpage lists American military electronic instruments/systems along with brief descriptions. This stand-alone list specifically identifies electronic devices which are assigned designations (names) according to the Joint Electronics Type Designation System (JETDS) beginning with the AN/ prefix. They are grouped below by the first designation letter following this prefix. The list is organized as sorted tables that reflect the purpose, uses and manufacturers of each listed item.

USAGE NOTE
LPI is crucial in modern warfare for stealth platforms and secure communications, enabling operations without revealing presence or intent to an adversary's detection systems.
