SYNTHETIC ANTIBACTERIAL PEPTIDES

Not Available The Army's increased utilization of passive intelligent acoustic sensors has created strong interest in optimizing their use in the modern battlefield. A complex acoustic propagation environment that varies in time and space, and diverse combat operations further complicate the problem. Planning Systems Incorporated (PSI) proposes to develop a Tactical Decision Aid (TDA) to guide the battlefield commander in the use of intelligent acoustic sensors and in interpretation of their results. In the past year PSI has successfully developed and demonstrated an acoustic TDA for Anti-Submarine Warfare (ASW) applications in the Near-Shore Tactical Reconnaissance (NSTR) program sponsored by the Defense Advanced Research Protects Agency (DARPA). In addition, PSI is currently making extensive use of the Mesoscale Meteorology Model (MM5) developed by the National Center for Atmospheric Research and Pennsylvania State University. This extensive experience base will be brought to bear on the TDA development. Although air acoustics and underwater acoustics have very different modeling requirements, both require the use of a high resolution rendering of the b MM5 and the use of a high fidelity acoustic propagation model that is dependent on range, azimuth, and elevation (or depth). PSI will adapt the technology and software architecture of NSTR to the air acoustic environment to build the Air Acoustic Tactical Decision Aid (AATDA) software. The operator will use the software's point and
