Raytheon announced on 17 July that its Low-Power Radar (LPR) is on track to begin initial production in 2019, after it demonstrated the ability of the active electronically scanned array (AESA), X-band system to provide precision approach guidance to aircraft from 15 n miles.
Originally developed as a weather radar, LPR is a compact (1 m2 ) solid-state unit. Its advanced dual-polarisation (horizontal and vertical) capability differentiates it from most in-service radars that use a single polarisation to transmit and receive.
Phased-array radars are also cheaper to maintain and offer adaptive beam scanning. LPR is a solid-state unit so it should be easier to maintain than legacy radars, “giving it longer lifetimes and lower life-cycle costs”, Raytheon stated.
