Abstract: |
The proposed Phase I investigation is expected to yield innovative technologies for covert active sonar operation for antisubmarine warfare. The approach includes an innovative active sonar concept, waveform selection, receive signal processing, and correction of signal distortion by environmental propagation. The low source level which enhances low probability of intercept will also provide marine mammal mitigation. 3 Phoenix has extensive experience in the development of sensor processing technology and has been successful in transitioning leading edge technology to defense applications. We anticipate that the results of this effort will demonstrate the feasibility of the system approach and the path to implementation. |
Benefits: |
The proposed Phase I investigation is demonstrate the feasibility of covert active sonar using continuous active transmission of spread spectrum waveforms. A significant component of the feasibility study is aimed at the acoustic detection challenges, and we propose to show that detection and tracking of submarines at tactically significant ranges is feasible using the proposed design and meets high probability of detection and false alarm rate requirements using low source levels. A second major component of the feasibility demonstration is that the proposed sonar system can be covert. Furthermore, we anticipate demonstration that the approach is realizable using current sonobuoy and sonar technology. |
