Popis: | In this paper, the problem of target masking induced by sidelobes arising in an OFDM RadCom System is considered. To fully exploit the waveform structure and address practical scenarios, we propose to deal with the sidelobes in the subband domain via sparse recovery. Accordingly, we design a sparsifying dictionary modeling at the same time the target's peak and pedestal (i.e., random sidelobes). Results on synthetic data show that our approach allows one to remove not only the target pedestal but also range ambiguities arising when all subbands are not active. |
