Signal performance comparison of different design methods.

RS design mode	Characteristic	Performance
Orthogonal frequency multiplexing [51]	(1) Optimised ambiguity function; (2) Low peak-to-average power ratio	(1) ACF SLL↓ from -15 to -20 dB; (2)
Nonsinusoidal RS design [52]	(1) Stealth targets; (2) Pulse compression with Barker codes	(1) Sidelobe free interval↑; (2) with time
Heisenberg nilpotent Lie group [53]	(1) Phase discontinuity of Fourier; (2) Chirp waveforms of microoptics	(1) FEB recaptured; (2) Transmitted at the rate of 2 W/s
Ambiguity function design [50]	(1) Discrete frequency-coded; (2) Synthesised polyphase	(1) increases from 3 to 6; (2) Transmitted at the rate of 2 W/s
