Enhanced Multistatic Active Sonar via Innovative Signal Processing

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
