New radar pulse compression waveforms

Pulse compression waveforms are described which have low sidelobe levels. Emphasis is on individual waveforms or multiple dissimilar waveforms. Processing the single waveforms consists of matched filtering while the multiple waveforms are individually matched, filtered, time-aligned, and summed. The multiple waveforms consist of complementary waveforms whose compressed pulses sum to zero in the sidelobes. These waveforms, in turn, were related to the underlying theory of orthogonal matrices. Multiple waveforms are discussed that, when filtered using a filter matched to a different waveform of the set, have a small output or cross-correlation response after combination of the individual responses. These waveforms have potential applications in reducing ambiguous range stationary clutter returns.<
