Pulsed active sonar (PAS) and continuous active sonar (CAS) in the presence of a strong direct blast are studied for the Doppler-tolerant linear frequency modulation waveform. A comparative analysis is done between PAS and CAS based on the range-Doppler and range-compression images obtained. Furthermore, a generalized likelihood ratio-based criterion is developed for moving target detection. CAS is further studied with a Doppler-sensitive SHAPE waveform, and weighted range-Doppler processing for CAS-SHAPE system is introduced.
