NEWBORN SCREENING BY MULTIPLEX MOLECULAR ANALYSIS

Not Available Active acoustic detection of underwater targets generally relies on reflection of the incoming sound energy. For a monostatic sonar attempting to detect a submarine target, the strongest signal return is a specular reflection from beam aspect. For a bistatic sonar, where the source and receiver are separated, the strongest return is a specular reflection. This SBIR proposes the exploitation of an additional signal path which is the result of acoustic scattering phenomena of targets. We believe this additional signal path will significantly increase the number of detection opportunities and will translate into increased mission effectiveness. The air ASW platform is the proposed commercial application for this technology. The air ASW platform is capable of deploying a distributed sonobuoy field which is ideally suited to take advantage of this signal. The existence of this signal path has been verified by the U.S. Navy. A few data samples of this scattering phenomena were obtained in one or two NAWC sea tests. This proposal provides an innovative approach to estimating the field performance improvement and the signal processing required to exploit this acoustic scattering phenomena.
