Abstract
Spread-spectrum techniques are used in radar and communications for simultaneous access to a common radio allocation with the minimum of interference or crosstalk. The authors review the concept of binary phase and frequency shift keyed sequences to derive the coded waveforms for these systems and examine their auto- and cross-ambiguity surface performance in the presence of Doppler shifted received signals. In particular, aperiodic sequences are investigated to obtain a set of coded waveforms with time-bandwidth products below 127
