Impact of Strong Direct Blast on Active Sonar Systems

You are here

Pulsed active sonar (PAS) and continuous active sonar (CAS) in the presence of 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. Further, a generalized likelihood ratio (GLR) based criterion is developed for moving target detection. CAS is further studied with a Doppler-sensitive SHAPE waveform and a weighted range-Doppler processing for CAS-SHAPE system is introduced.
