A Study on Detection Probability Reduction of LPI Radar's Platform
The Journal of the Korean Institute of Information and Communication Engineering, 2014 In General, LPI radar’s detection probability by ES equipments is lower than that of conventional pulsed radar because of very low transmitting power and high antenna gain etc. LPI radar is a kind of RF stealth technique such as RCS reduction design. Therefore the ultimate goal of LPI radar is detection probability reduction by opponent.
