Abstract: In this paper, to counter a new generation of stealth aircraft target as the breakthrough point, based on stealth target multi-band, single/double station target scattering evaluation and analysis, it shows that in low frequency and high frequency band, as well as multi-station, target's RCS significantly becomes larger, which provides a direct theoretical basis for the selection of antistealth radar frequency and system. Whereby, the anti-stealth technology roadmap and target detection development proposals, including the extended frequency band and detection perspective, the use of multi-sensor hybrid network, as well as the development of new broadband and passive systems, are proposed.
