Description

The Office of Naval Research (ONR) announces the release of a draft specification for the Array Wet Subsystem (AWS) se gment of the Acoustic Observatory (AO) Robust Passive Sensor (RPS). The AO RPS has the exploratory development objective of defining the spatial and temporal properties of the shallow water environment that pose the fundamental limit to the perform ance of passive sonar systems. In addition, the AO RPS has the equally important engineering objective of optimizing spatio- temporal signal processing methods for an environmentally matched spatial aperture configured as either a mobile towed or a fixed deployed array of hydrophones. ONR encourages the teaming of interested organizations in response to anticipated Reque st for Proposals (RFPs) for the following: Array Wet Subsystem (AWS) ? The AWS has a notional concept that includes a large planar Horizontal Array Segment (HAS) consi sting of either a Suspended Array Segment (SAS) or a Bottomed Array Segment (BAS) which are configured from multiple modular horizontal parallel line arrays. The HAS shall be connected to a shore based Trunk Termination Segment (TTS) by means of th e Observatory Trunk Segment (OTS). Additionally, the AWS includes two independent, on-board and off-board, systems for hydro phone Array Element Location (AEL). The on-board AEL subsystem contains only components integral to the array modules and th e off-board AEL can contain bottom mounted transmit-receive units. The HAS notional concept envisions a recoverable and rec onfigurable array composed of linear hydrophone array modules that can be deployed as either a long multiline array aperture or a less lengthy Vertical ?billboard? Array Segment (VAS). The draft specification is available at http://www.onr.navy.mil/sci_tech/ocean/321_sensing/prog_us.htm. Requests for hard c opies of the draft specification will be disregarded. Public comments on the draft specification will be accepted through C OB December 10, 2001. Comments should be submitted electronically to the following e-mail address: aoawsrfi@onr.navy.mil. It is not the intention of the Government to respond to comments individually. Additional questions or inquiries should be directed to Brian Glance via telephone at (703)696-2596 or via e-mail at glanceb@onr.navy.mil.
