"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 (ARMs). LPI measures include:"@en . . . . . . . . . . . "10237"^^ . . . . .

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 (ARMs). LPI measures include: \n* Power management and high duty cycle, meaning the transmitter is on most of the time (long integration times) \n* Wide bandwidth (or Ultra-wideband) \n* Frequency Agility, and frequency selection \n* Advanced/irregular scan patterns \n* Coded pulses (coherent detection) \n* High processing gain \n* Low sidelobe antennas"@en .
