Abstract:

For the problem of the low computational efficiency in the existing CSA based on MSR for the multiple-receiver SAS because it is required to perform image reconstruction for each receiver, an efficiency CSA based on MSR for the multiple-receiver SAS is proposed in this paper. Firstly, to make that the range cell migration, azimuth modulation, and range modulation of different receiver can be represented by that of the reference receiver, the signal of each receiver is shifted to the same shortest range. Secondly, to obtain the imaging result by performing one imaging reconstruction, the multiple receivers signal shifted is transformed into the monostatic signal by azimuth reconstruction. Thirdly, the imaging reconstruction based on MSR's 2D spectrum is derived by utilizing the chirp scaling principle. Finally, the effectiveness of the proposed algorithm is validated by the simulation experiments.

I. Introduction (Heading 1)

Synthetic aperture sonar (SAS) is an remote sensing technology that has a centimeter resolution over hundreds-over-meter range on the seafloor [1]. Although the provenance of SAS comes from synthetic aperture radar (SAR), the slow speed of sound in water cause them to be two difference [2], [3]. The one key difference is that the move distance during transmission and reception should be taken into account in SAS, referred to as the non-stop-hop-stop mode [4]. The other key difference is that SAS should be configured an array of receivers for a useful mapping rate requires, referred to as the multiple-receiver SAS.
