LPD
LPD, or Low Probability of Detection, refers to a characteristic of signals or systems designed to be very difficult for an enemy to spot or intercept, often by blending into background noise or being very weak. It's a key feature in stealth technology and secure communication to avoid being noticed.
TECHNICAL DEFINITION
Low Probability of Detection (LPD) describes an electromagnetic signal characteristic or system design methodology aimed at minimizing the likelihood of interception or detection by adversary electronic support measures (ESM) systems. LPD techniques, critical in electronic warfare (EW), intelligence, surveillance, and reconnaissance (ISR), and secure communications, often employ spread spectrum, low power, directional transmission, or specific modulation schemes to reduce spectral density and enhance covertness against radar and communication intelligence.
BACKGROUND
The San Antonio class is a class of amphibious transport docks, also called a "landing platform, dock" (LPD), used by the United States Navy. These warships replace the Austin-class LPDs, as well as the Newport-class tank landing ships, the Anchorage-class dock landing ships, and the Charleston-class amphibious cargo ships that have already been retired.

USAGE NOTE
LPD is a critical design goal for stealth aircraft radar, secure tactical radios, and unmanned aerial vehicle (UAV) datalinks to evade adversary detection and targeting.
