A set of code sequences is proposed for radar applications in which all phase steps are equal and the time duration of each phase state is varied in order to properly approximate either a stepped-RE waveform or a linear FM waveform, Since these proposed waveforms have varying time durations at each phase state, they are referred to as "polytime" codes. polytime code sequences have the advantage that arbitrary time-bandwidth waveforms can be generated with a few phase states. Of particular interest are cases where phase is quantized into two states (i.e., 0 degrees and 180 degrees).
