In this chapter, we shall investigate the design and performance of phase-coded signals that have also found popularity in LPI radar waveform compression design. In the class of phase-coded signals, there is a wide variety. This class of signals transmits at one frequency, but changes the phase as it transmits in a predetermined order.
