Abstract
The theoretical performance of different active sonar pulse types is examined through the use of ambiguity functions, cross-ambiguity functions, and Q-functions. The commonly used continuous wave (CW) and frequency modulated (FM) waveforms are reviewed, along with more complex wave forms and pulse sequences designed to superior reverberation performance or Doppler/range resolution, including sinusoidally frequency modulated (SFM) waves and frequency hopped trains of pulses, such as Costas codes and quadratic congruential codes.
