“…In [ 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 ], in order to solve the problem of target masking caused by high sidelobes in the range-Doppler domain, different optimization algorithms have been designed for sidelobe suppression. Tao Fan [ 15 ] et al designed a Doppler filter bank for non-uniform pulse repetition interval (PRI) radar to suppress clutters. For radar to coexist with other wireless systems, Khaled Alhujaili et al optimized the transmit beam pattern for multiple-input multiple-output (MIMO) radar in [ 16 ].…”

In this paper, a new radar signal modulated with a hybrid of the frequency shift keying (FSK) and the phase shift keying (PSK) signal—i.e., the FSK-PSK signal—is studied. Different phase encoding sequences are used to modulate the sub-pulses to obtain lower sidelobe levels and ensure signal orthogonality. In addition, to counter intra-pulse slice repeater jamming of specific length generated by the enemy jammer, an orthogonal waveform made of sub-pulses of equal length based on the FSK-PSK modulation scheme is designed. The simulation results show that the optimized discrete phase encoding sequence can significantly enhance the orthogonality of the sub-pulse in the FSK-PSK signal and effectively suppress the slice repeater jamming. Two algorithms are proposed: (1) the low sidelobe waveform optimization algorithm based on ADMM (LSW-ADMM); and (2) the anti-slice-repeater-jamming algorithm based on ADMM (ASRJ-ADMM). Both algorithms exhibit fast convergence speed and low computational complexity.
