The Front-end Electronics LRU is designed to process and store various sensor parameters from the SONAR. The signal will be processed using Zynq Ultrascale+MPSoC.
The Multichannel Front-end Electronics for SONAR consists of four cards namely power supply card, either two signal conditioning card or two pre-amplifier card and one controller card.
Mission Control Unit is designed to acquire various sensor signals located in the Torpedo. The acquired signals will be processed by the Artix-7 FPGA and the TMS320 processor.
Mission Control Unit (MCU) is a microcontroller and FPGA based real time interface module that consists of,
1. CPU card
2. Power Distribution Card
3. Mother Board
Instrumentation System relates to underwater decoys and more particularly to a device when placed in the underwater which also emits signals and navigates similar to those produced by a submarine.
The low power embedded processing system is realized by integrating the developed Xilinx Zynq Ultrascale+ FPGA 3U Rugged System Unit in a 4-Slot 3U VPX chassis. The form factor of the board is 3U VPX, and also 3U VPX Conduction cooled Gigabit Ethernet switch with 16 Gigabit ports with 9K jumbo frame support and L200 ruggedisation level is used to communicate within and external to the system.
Multichannel DAS is used to acquire hydrophone signals of frequency range 1Hz to 25kHz with 8 channels and maximum of 16 channels. The recording system has a delta-sigma A/D converter that provides digital antialias filtering and data to be stored in integrated Solid State Drive (SSD). The complete system power is controlled by microcontroller based power management unit and it is built around low power processor with various interfaces such as DDR, Flash, RTC, Ethernet, USB, RS232, SATA, and Sigma-Delta simultaneous ADC.
