Abstract

This study addresses the deception and suppression jamming by developing waveform design strategies for the networked radar system. To this end, we assume that the extended target radar cross section (RCS), signal-dependent clutter, false target frequency response, and suppression jamming frequency distribution are known, and then derive the signal-to-jamming-plus-noise ratio (SINR) and mutual information (MI) expressions in regard to extend target in the presence of the two kinds of jamming. Considering the practical application of networked radar with the constraint of transmission power, two optimal waveform design models are formulated to maximize the contaminated SINR and MI respectively. Subsequently, the Lagrange multiplier method is resorted to figure out the optimal waveform design model. Finally, the simulation results are demonstrated to verify the proposed waveform design can effectively improve SINR and MI compared with some other signals when the two kinds of jamming exist.
