Clutter-Masked Waveform Design for LPI/LPD Radarcom Signal Encoding

Abstract: In this work we propose a method of in situ clutter deconvolution and modeling using experimentally obtained UWB radar data. The obtained clutter models are then used for random sequence encoding of radar-communication (radarcom) signals to achieve clutter-masked transmissions and improve communication security. We present the results of clutter modeling from the laboratory data obtained with the software-defined radar system. We then show that such clutter-masked radarcom signals generated using the local clu… Show more

“…Furthermore, since the bistatic radar receiver employs the self-synchronization scheme, the reconstruction of the FM waveform suffers in the presence of noise, especially if SNR is less than 3 dB. The quality of the simulated cross-ambiguity functions in the presence of noise can be evaluated using the sidelobe volume function [67] given in Equation (17). For an ideal thumbtack ambiguity function, V SL should be equal to zero.…”

“…In this letter, we will use the NSGA-II to create an OFDM radarcom signal with weighted and optimized PSLR, peak-to-average power ratio (PAPR), LPI, radar detection/identification, and communication bit error rate (BER) parameters. We also propose to achieve the characteristic of LPI via masking our transmissions as local radar clutter [17], which is implemented via a random sequence encoding (RSE) [18].…”
