What is Low Probability of Intercept mean?
A low-probability-of-intercept radar (LPIR) is a radar employing measures to avoid detection by passive radar detection equipment (such as a radar warning receiver (RWR), or electronic support receiver) while it is searching for a target or engaged in target tracking. This characteristic is desirable in a radar because it allows finding and tracking an opponent without alerting them to the radar's presence. This also protects the radar installation from anti-radiation missiles (ARM).
LPI measures include:
Power management and high duty cycle, meaning the transmitter is on most of the time. (long integration times)Wide bandwidth (or Ultra-wideband)Frequency Agility, and frequency selectionAdvanced/irregular scan patternsCoded pulses (coherent detection)High processing gainLow sidelobe antennas referencePosted on 15 Dec 2024, this text provides information on Miscellaneous in Electronics related to Electronics.
