Abstract

Abstract:

In the presence of false-target deception jamming, the anti-jamming ability of monostatic radar is limited, and anti-jamming methods based on data fusion cannot fully exhaust the anti-jamming ability of netted radar due to the high information loss rate at the data level. Echoes of true targets are essentially independent, when they are received by node radars from sufficiently different directions due to the fluctuations of target radar cross section (RCS). However, deception jamming signals received from different directions would be highly coherent. Exploiting this difference, an active false-target discrimination method for netted radar based on target spatial scattering characteristics is proposed, in which a correlation test is implemented between slow-time complex envelope sequences of different targets to discriminate active false-targets. Simulation results indicate that the approach proposed can effectively discriminate false-targets and ensure the recognition probability of true targets.
