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.
The diagram on the left shows the effect on the spectrum if a trapezoid pulse profile is adopted. It can be seen that the energy in the sidebands is significantly reduced compared to the main lobe and the amplitude of the main lobe is increased. Radar transmission frequency spectrum of a cosine pulse profile
Light surface below wing edges is the AN/APQ-181 radar antenna. The AN/APQ-181 is an all-weather, low probability of intercept (LPI) phased array radar system designed by Hughes Aircraft (now Raytheon) for the U.S. Air Force B-2A Spirit bomber aircraft. The system was developed in the mid-1980s and entered service in 1993.
The AN/APG-77 is a multifunction low probability of intercept radar installed on the F-22 Raptor fighter aircraft. The radar was designed and initially built by Westinghouse and Texas Instruments, and production continued with their respective successors Northrop Grumman and Raytheon after acquisition.
Low-probability-of-intercept radar – Radar technology that hides its activity from a detected target; No. 100 Group RAF – Former Royal Air Force operations group; Pelena-1 – Russian ground-based jamming system; Radio jamming – Interference with authorized wireless communications; Suppression of Enemy Air Defenses – Military tactic
The EL/M-2248 MF-STAR is a GaN based multifunction active electronically scanned array naval radar system developed by IAI Elta for maritime installation on warships. [3] It is capable of tracking both air and surface targets and providing fire control guidance. MF-STAR is an acronym of Multi-Function Surveillance, Track And Guidance Radar. [4]
Such a system is referred to as a low-probability-of-intercept radar. [39] [40] In other applications, such as microwave links, the transmitter's antenna may never point at the DF receiver at all, so reception is only possible by means of the signal leakage from antenna side lobes.
A plan position indicator (PPI) is a type of radar display that represents the radar antenna in the center of the display, with the distance from it and height above ground drawn as concentric circles. As the radar antenna rotates, a radial trace on the PPI sweeps in unison with it about the center point. It is the most common type of radar ...
