Abstract:

Our objectives are 1 to consider multistatic continuous active sonar MCAS systems, aka high duty cycle systems, that involve the transmission and reception of multiple continuous probing sequences or long duty cycle sequences 2 to investigate the merits of MCAS on its ability to achieve significantly enhanced target detection and parameter estimation performance through exploiting the advantages of continuous illumination and spatial diversity 3 to develop innovative techniques to synthesize spectrally contained continuous sequence sets with low correlation sidelobe levels for the MCAS transmission, so that the so-generated sequences meet the spectral containment restrictions and the weak correlations among the received echoes can be exploited to improve the target detection performance, and 4 to apply robust, computationally efficient, and data-adaptive receiver signal processing algorithms to effectively mitigate the mutual interferences among multiple transmitters and suppress direct blasts for MCAS systems
