Robust wideband waveform design with constant modulus and discrete phase constraints for distributed precision jamming

• The proposed robust wideband waveform design explicitly addresses the worst-case combined power spectrum (CPS) for both opponent and friendly devices, ensuring effective jamming while protecting adjacent friendly electronics. • A large-scale minimax multi-objective optimization problem is efficiently transformed into a single-objective Lp-norm/Pareto framework, simplifying tractability. • The RCG-CMDPC algorithm leverages Riemannian conjugate gradient on complex circle manifolds to enforce constant modulus and discrete phase constraints, achieving low computational complexity. • Numerical experiments demonstrate superior robust DPJ effectiveness and computational efficiency compared to existing waveform design approaches.
