Adaptive beamforming (ABF) for maximizing the signal to interference plus noise ratio (SINR) is applied to acquisitions made by a passive bistatic radar (PBR) exposed to strong direct signal interference (DSI). The DVB-T transmitter was located appro

2017 18th International Radar Symposium (IRS).
A dual-polarization passive bistatic radar is used to evaluate the potential benefit of cross-polarized measurements for the suppression of strong direct signal interference in the DVB-T band. The linear array antenna consists of 10 bowtie elements,

The work presented in this chapter has shown how to take advantage of the microDoppler features of the rotary parts of a helicopter. Traditionally, analysis of the amplitude variations of the target echo returns have been used in order to separate fi

A statistical method to predict the stochastic evolution of corrosion fronts has been developed. The method is based on recording material loss and maximum front depth. In this paper we introduce the method and test its applicability. In the absence
