A new complementary waveform technique for radar signals

A new phase coding technique for radar signals is introduced which uses novel complementary waveforms constructed to have optimal sidelobe performance. The waveforms are constructed using a modification of the Prometheus orthonormal set (PONS) technique. An advantage of a PONS matrix is that it allows for many complementary pairs of waveforms to choose from as well as allowing for multiple pairs to be used simultaneously. It is shown that sets of waveforms which are complementary in quartets can also be applied for more flexibility. Results showing improved ambiguity properties versus other radar waveform coding techniques are given.
