Target Signature Extraction Using Truncated Singular Value Decomposition for Electronic Protection

Recent studies show that jamming suppression can be performed using modified matched filters that are matched to the transmit waveform - target response (TWTR). In many radar applications the target backscattering is reduced to a scalar factor, which is mainly related to the radar cross section (RCS). Our interest is to obtain bandlimited extended target impulse responses via time-domain analysis of backscattered signals from simulations and open field measurements. In other words, our goal is to extract the extended response-signature from an actual target. We propose to use truncated singular value decomposition (TSVD) to extract the target signatures from TWTR. In our application, the target signature is exploited to mitigate the effect of coherent jammer for electronic protection (EP).
